Leaf venation is of the striate type, mainly arcuate-striate or longitudinally striate (parallel), less often palmate-striate or pinnate-striate with the leaf veins emerging at the leaf base and then running together at the apices. There is usually only one leaf per node because the leaf base encompasses more than half the circumference. The evolution of this monocot characteristic has been attributed to developmental differences in early zonal differentiation rather than meristem activity (leaf base theory).

In the development of mammalian visual system, axons from each eyes crosses through the lateral geniculate nucleus (LGN) and terminate in separate layers of striate cortex. However, axons from each LGN can only be driven by one side of the eye, but not both together. These axons that terminate in layer IV of the striate cortex result in ocular dominance columns. A study shows that The density of innervating axons in layer IV from LGN can be increased by exogenous BDNF and reduced by a scavenger of endogenous BDNF.

VI p. 74-75; 1884 (described as Conus cancellatus) This is a variable species, yet two distinct forms are recognized: (1) sowerbii form, Reeve, 1849 (a thicker, darker, and more densely spotted form with 2 protoconch whorls), and (2) aliguay form, Olivera & Biggs, 2010 (2.5 pearly white smooth protoconch whorls, more slender, higher spire, rounded shoulders, lighter colored).
Blindsight is the ability of people who are cortically blind due to lesions in their striate cortex, also known as the primary visual cortex or V1, to respond to visual stimuli that they do not consciously see. The majority of studies on blindsight are conducted on patients who have the conscious blindness on only one side of their visual field. Following the destruction of the striate cortex, patients are asked to detect, localize, and discriminate amongst visual stimuli that are presented to their blind side, often in a forced-response or guessing situation, even though they do not consciously recognize the visual stimulus. Research shows that blind patients achieve a higher accuracy than would be expected from chance alone.
The Cadellia is one of four sections of the Fables clade. Its pollen is prolate spheroidal, striate with a granular aperture surface membrane. Pollen morphology has linked the Surianaceae in a clade comprising Polygalaceae, Fabaceae, and Quillaja.

Originally, this fossil was described as Oscillatoriopsis rhomboidalis Sivertzeva, 1985 on the basis of a specimens from Torozhma borehole, Arkhangelsk Region, Russia. Later, the species O. rhomboidalis was reassigned to the separate genus Pomoria Sivertzeva et Jankauskas, 1989. Pomoria is distinguished from other fossil trichomes by a thin longitudinal or diagonal striate sculpture.
The surface is slightly striate above, and on the first half of the base. The last half whorl is regularly latticed or malleate in a diamond pattern. The shell has 5 whorls; the first one is flattened. The last half-whorl is straightened out: it runs to the periphery and is then upturned.

Shortly after Hubel and Wiesel included hypercomplexity into their version of the visual processing hierarchy, the notion of a class of hypercomplex cells was contended. In 1968, Geoffrey Henry and Bogdan Dreher discovered simple and complex cells in Brodmann area 17 that exhibited end-stopping properties.Dreher, B. (1972). Hypercoplex cells in the cat's striate cortex.
Most are gray or brown, but a few species have brighter colors. Most have a translucent and striate cap, which rarely has an incurved margin. The gills are attached and usually have cystidia. Some species, like Mycena haematopus, exude a latex when the stem is broken, and many species have a chlorine-like odor.
A trace of the first keel anterior to the periphery may be seen above the suture in several of the last whorls. The white interstices are striate. The periphery of the body whorl is marked by the anterior edge of the third channel. The next keel anterior to this is like those between the sutures.
Its color pattern is olive-green or brownish. The 6–7 whorls are slightly convex, obliquely finely striate, longitudinally finely plicate. The folds stand at right angles to the striae, and are interrupted one-third of the distance from the suture to the periphery by two spiral impressed furrows. The linear suture is undulating.

It becomes blue when bruised. The gills are adnexed, distinctly mottled, and dully grayish with blackish spots.
When non-motor cerebral cortex excites the striate body, the caudate and putamen specifically inhibit neurons in the globus pallidus and subthalamus. This specific disinhibition enables movement initiation, by releasing excitatory thalamic neurons. ; Ventral striatum Functionally strongly associated with emotional and motivational aspects of behavior. Strongly innervated by dopaminergic fibers from the ventral tegmental area (VTA).

Compressed, moderately involute shell with keel and narrow venter. Cross section of whorl is elliptical, with rounded umbilical edge and sloping umbilical wall. Falcoid, or sinuous ribs are weak, or moderate on inner whorls, while on outer whorls, they are becoming striate, or these whorls are smooth. Diameter of complete adult shell is 120–250 mm.
The cap is sometimes translucent-striate near the margin, often with an umbo. It usually stains blue or black in age. The gills are cream-colored when young, violet brown in age, with a subsinuate or adnate attachment. Psilocybe villarrealiae spores are dark violet brown, oblong to ellipsoid or subrhomboid, thin-walled, and 7 x 4 µm.
The fasciole is ornamented by spaced, delicate, concave riblets. Fine arcuate growth lines appear in the interstices of the spiral keels. In the protoconch, the first wliorl and a half are small, rounded, and spirally striate. The rest protrude medially, and are crossed by fine sharp radial riblets, which on the last whorl number twenty-two.
The primary visual cortex is the most studied visual area in the brain. In mammals, it is located in the posterior pole of the occipital lobe and is the simplest, earliest cortical visual area. It is highly specialized for processing information about static and moving objects and is excellent in pattern recognition. The primary visual cortex, which is defined by its function or stage in the visual system, is approximately equivalent to the striate cortex, also known as Brodmann area 17, which is defined by its anatomical location. The name "striate cortex" is derived from the line of Gennari, a distinctive stripe visible to the naked eyeGlickstein M., Rizzolatti G. Francesco Gennari and the structure of the cerebral cortex Trends in Neurosciences, Volume 7, Issue 12, 464–467, 1 December 1984.
Above the keels they are finely arcuately striate, below irregularly more or less crenately concentrically ridged . The aperture is triangularly subquadrate, pure white, and shining within. The white columella is smooth, slightly arcuate above, nearly straight below. The outer lip shows a broad excavated sinus extending from its juncture with the body whorl to the extremity of the last keel.
The size of the shell varies between 25 mm and 60 mm. The short spire is conical and tuberculate. The color of the shell is uniformly brown, lineated with chocolate, with sometimes longitudinal white maculations forming a broad central interrupted band, and a few additional maculations on other portions of the surface. The base of the shell is subgranularly striate.
The size of the shell varies between 16 mm and 65 mm. The short spire is conical and tuberculate. The color of the shell is chestnut-brown, lineated with chocolate, with sometimes longitudinal white maculations forming a broad central interrupted band, and a few additional maculations on other portions of the surface. The base of the shell is subgranularly striate.
It is more involute than Cleviceras exaratum and Eleganticeras elegantulum, but as it is evolved directly from C. exaratum, there exists some transitional specimens. Also, C. exaratum has vertical, or undercut umbilical walls, while C. elegans has them bevelled, or sloping. C. elegans also has weaker and more striate ribs at sizes below 30mm diameter. Then, ribbing is the same.
Conocybe tenera is a small saprotrophic mushroom with a conic to convex cap and is smooth and colored cinnamon brown. It is usually less than 2 cm across and is striate almost to the center. The gills are adnate and colored pale brown, darkening in age. The spores are yellowish brown, smooth and ellipsoid with a germ pore, measuring 12 x 6 micrometres.
They recorded 1410 cells in 45 penetrations into the striate cortex. Through this 1-dimensional technique they conceptualized that the orientation columns are not columns but slabs. In 1985, Gary Blasdel discovered a technique to visualize these orientation columns in 2D. His technique used photodiodes to detect optical changes in the visual cortex with the metabolic marker, 2-deoxyglucose, which labels active neurons.
The cap is convex initially, but later flattens and becomes depressed with a wavy edges. The centre of mature fruiting bodies is noticeably scurfy, or scaly. This is a feature that is best seen on dry specimens, that have not been rained on. The cap colour is scarlet-orange with a yellow striate margin, and is 0.5–3.5 cm in diameter.
The cap is in diameter, bell-shaped to subumbonate, smooth, and slightly slimy but soon dry. The color may range from a pale orange-brown to a deep rusty brown. It is hygrophanous, fading to buff; the color is blackish brown when dry, and slightly translucent-striate when wet. Like other hallucinogenic psilocybes, it stains blue when bruised or injured.
As in earlier studies, electrophysiological findings were complemented by monkey and human psychophysics.De Valois, R.L., Morgan, H.C. & Snodderly, D.M., "Psychophysical studies of monkey vision III. Spatial luminance contrast sensitivity tests of macaque and human observers", Vision Res. 14: 75-81 (1974) Well into his 70s, De Valois continued to pursue the transformations of visual information in LGN and striate cortex.
Basidiocarps may range in color from bright yellow, red, or orange, to purple, white, and shades of tan. Color changes after bruising occur in some species. The spores of Ramaria species are yellow-brown to rusty-brown in mass deposit and range from smooth to warted to echinulate or striate; spore size may range considerably, and ornamentation, when present, is cyanophilous.
The fruit bodies of Melanoleuca are small to medium size (pileus 10–120 mm in diameter). The pileus is convex becoming depressed at the center, it is usually dry and white, brown, ocher, or grey. The gills are adnexed, sinuate, adnate, or subdecurrent, white to yellowish. The stipe is central, cylindrical or slightly swollen at the base, dry and longitudinally striate.
The spiral lirae number about 6 on each whorl, but often double as many, by the intercalation of riblets in the interstices. The periphery has a prominent keel, cord-like, with secondary spiral striae, or bifid, cut into compressed granules, somewhat prominent above the sutures. The base has about 8 concentric ribs. The interstices are radiately striate, sometimes with a central riblet.
The occipital lobe is divided into several functional visual areas. Each visual area contains a full map of the visual world. Although there are no anatomical markers distinguishing these areas (except for the prominent striations in the striate cortex), physiologists have used electrode recordings to divide the cortex into different functional regions. The first functional area is the primary visual cortex.
Sphagnurus paluster can be white pruinose when young and does not stain or bruise when crushed. Its flesh is thin, soft, and watery. The cap is in diameter, starting as conical or bell shape when young, expanding flat with a distinct umbo when older. It is smooth, striate, and hygrophanous; usually an olive-brown when moist, drying to a pale grey color.
Desmoglein 1 haploinsufficiency leads to striate palmoplantar keratoderma, a disease which causes extreme thickening of the epidermis. Loss of desmoglein 4 leads to defective hair-follicle differentiation. Epidermolysis bullosa simplex is an epidermal blistering disease caused by mutations in genes coding for keratin 5 and 14, which attach to desmoplakin. This disease manifests as rupture of the basal epidermis when stress is applied.
The shell is deeply perforate, long-ovate, regularly finely striate, very glossy and reddish-brown in color. The shell has 5½ convex whorls. The last whorl is about equal to the penult, which is a third higher than the preceding whorl, which is double the height of the next earlier. Last whorl has a transverse callus of the same color near the aperture.
The sutures are subcanaliculate. The acute apex is eroded. The following whorls are finely granose in spiral series, of which there are 10 to 12 on each whorl. The body whorl is somewhat deflected anteriorly, bearing about 30 spiral granose ridges, very close and fine upon and below the periphery, coarser above and around the umbilicus, the interstices obliquely striate.
Tetragonitidae is a family of Cretaceous lytoceratin ammonites typically with square or trapezoidal whorl section at least during some growth stage. Members of this family are usually smooth but some lirate or striate, often with constrictions. Other features include suture with a varying number of auxiliary saddles, and an internal suture with two or more. Major saddles are irregularly trifid.
The body whorl contains about 17 to 21 closely beaded cinguli, of which the 8th or 9th usually forms the peripheral angle, all above that being subequal and equally spaced. Those of the base are more crowded and finer ; the interstices are sharply, finely obliquely striate. The body whorl is deflected toward the aperture, and appearing gibbous. The aperture is subhorizontal, and subtetragonal.
Another example is Pseudolioceras, whose unkeeled specimen was used as type for description of invalid genus Praehaploceras. Oxyconic forms of this subfamily (Polyplectus and Sphenarpites) does not have any keel. Ribs were single, but in some genera also bifurcating with shapes from sigmoidal to falcate. Sometimes, shell can have only striate ribs or is smooth (Sphenarpites and older specimens of Eleganticeras and Ovaticeras).
In the normal feline, about 85% of cells are responsive to input to both eyes; in the monocularly-deprived animals, no cells receive input from both eyes.Wiesel, T.N. and Hubel, D.H. (1963) Single cell responses in striate cortex of kittens deprived of vision in one eye. J. Neurophysiol., 26: 1003-1017 The monocular deprivation often leads to amblyopia that is irreversible.
The shell is rimate, turreted, irregularly and very finely striate, of reddish-brown color, glossy. The shell has 6 whorls, that are slowly increasing and rather convex. The first 3 whorls form a blunt summit which is about ⅓ the length of the shell. The last 3 whorls are of nearly equal height and form the remaining cylindric part of the shell.
Sulci are divided into following categories: On the basis of function: #A limiting sulcus separates at its floor into two areas which are different functionally and structurally e.g. central sulcus between the motor and sensory areas. #Axial sulcus develops in the long axis of a rapidly growing homogeneous area e.g. postcalcarine sulcus in the long axis of the striate area.
They are all over obliquely minutely striate. encircled by minutely granulose lirae, with smaller ones intercalated. The three first whorls are but little projecting, the fourth is double the length of the first three, the last whorl is inflated. The penultimate and last whorls contain a median series of reddish-brown quadrangular maculations or have the spiral lirae articulated with brown.
This theory is supported by findings that parafoveal retinal lesions deprive a region of striate cortex of visual input, and as a result, the receptive fields of neurons near the boundary of the deprived cortical region enlarge and expand into nearby regions of the visual field. Thus, polyopia results from altered coding of contour information by neurons near the lesioned area. This mechanism offers that after a focal lesion of neurons in striate cortex, or following a retinal lesion depriving these neurons of visual input, the receptive fields of nearby healthy neurons converge to code information about contours of objects normally coded by the damaged neurons while still coding the same information about retinal location prior to the injury. This mechanism may explain why polyopia extending into a patient’s scotoma occurs following damage to primary visual cortex.
Psilocybe authority Gastón Guzmán classified the species in the section Semilanceatae, a grouping of related species characterized by having roughly ellipsoid, usually thick-walled spores, and lacking pleurocystidia.Guzmán (1983), p. 342. The specific epithet pelliculosa is derived from the Latin pellicula, meaning "film", and refers to the gelatinous pellicle of the cap. The mushroom is commonly known as the "conifer Psilocybe" or the "striate Psilocybe".
The body whorl is long and rather cylindrical, closely striate below. The color of the shell is white, clouded with bluish ash, orange-brown, chestnut or chocolate, everywhere encircled by narrow chocolate interrupted lines, often separated into somewhat distant dots The middle of the body whorl is usually irregularly fasciate with white. The spire is tessellated with chestnut or chocolate.George Washington Tryon, Manual of Conchology vol.
The incremental lines are sharp, sometimes almost threadlike. The spiral sculpture consists of (from three to five on the spire, about 10 on the body whorl) strong, rounded cords overriding the ribs and not swollen at the intersections. The interspaces are subequal and sometimes with an intercalated smaller thread. Lastly the surface is finely minutely spirally striate in the intervals between the larger threads and cords.
On the body there are about twenty spirals, stronger at the shoulder, smaller and closer forward, the wide interspaces finely spirally striate, while the most prominent spirals are undulate or obscurely nodulous. The transverse sculpture is nearly obsolete and hardly to be distinguished from the incremental lines. The aperture is elongate and oval. The outer lip is thin, sharp, crenulated by the sculpture, but not lirate.
The size of an adult shell varies between 40 mm and 93 mm. The thin shell has a depressed carinate and striate spire, which is yellowish, maculated with brown. The body whorl is striated below, yellowish, with two series of longitudinal forked and irregular dark brown markings, interrupted in the middle and at the base. There are traces of distant narrow brown revolving lines.
The size of an adult shell varies between 50 mm and 98 mm. Its low spire is striate, flamed with chocolate and white. The body whorl is yellowish, or orange-brown, encircled by rows of chestnut dots, usually stained chocolate at the base. There is a central white band, with chocolate hieroglyphic markings on either side, and a shoulder-band, crossed by chocolate smaller longitudinal markings.
Shell fragments are known that would suggest a maximum size around 77 mm. The shell is regularly grooved throughout the body whorl, with the interstices plane or granular. The spire is striate, often gradate. The color is orange- red, raised portions with very narrow chestnut revolving lines, white clouded, especially in the middle, forming an irregular band, which is mottled and bordered with chestnut.
The size of an adult shell varies between 40 mm and 107 mm. The low spire is striate, flamed with chocolate and white. The body whorl is yellowish, or orange-brown, encircled by rows of chestnut dots, usually stained chocolate at the base. There is a central white band, with chocolate hieroglyphic markings on either side, and a shoulder band, crossed by chocolate smaller longitudinal markings.
The physical description is as follows: The cap is 25–65 mm wide, plano-convex to plano-depressed, buff, non-viscid, with a striate margin. The volval remnants are pulverulent on the center raised into wart- like peaksor warts or radial ridges, colored pale sepiAmanita. Gills are crowded and free, measure 6–7 millimeters wide, and appear white to pale buff. The short gills are subtruncate.
So by removing a few LGN inputs and adding a few, the orientation selectivity can be changed marginally. Ocular dominance columns are also found in the striate cortex. These columns were found to prefer crossing iso-orientation lines perpendicularly. During microelectrode experiments, it is normal to see penetrations where eye dominance changes between the contralateral eye and ipsilateral eye but this does not interrupt the orientation sequence.
Entoloma mammosum, commonly known as the bell-shaped Nolanea, is a species of fungus in the family Entolomataceae. The fruit bodies are small and nippled, with a striate cap, salmon-colored gills, and a stately stalk. It is typically found growing in feather moss under spruce and Jack pine in the summer and fall. It is saprobic, and derives nutrients from rotting organic matter.
The outlines of the spire is nearly rectilinear. The 7 to 8 whorls are planulate, very obliquely striate, radiately corrugated, and covered with a very minute secondary sculpture of radiating, fine, close wrinkles. The body whorl is acutely carinated at the periphery. The base of the shell is concave, concentrically lirate, the lirae about 6 to 8 in number, granose in the young, nearlysmooth in the adult.
The solid shell has a depressed-conical shape. The outer surface is sharply, spirally striate and closely obliquely striated . The shell has a more or less developed callous ridge or funicle revolving on the inner side of the whorl within the umbilicus, and terminating at the columella, the edge of which is reflexed over it. The sinuous columella terminates in a point or denticle at its base.
The surface of the shell is covered with narrow spiral closely and conspicuously beaded ridges, numbering 8-12 on the penultimate whorl, sometimes equal in size, sometimes alternately larger and smaller. On the next earlier (antepenultimate) whorl there are about 7, and still earlier whorls have 3 beaded carinae. The interstices are obliquely striate. The spire is a little concave in outline toward the apex.
The upper angle is acute, continuing nearly to the apex. The whorls are concave above, slightly excavated around the periphery, a little convex beneath. They are encircled by numerous unequal spiral threads, the larger ones beaded, the smaller irregularly crenated by rather decided incremental striae. The base of the shell is radiately striate, with about 8 to 12 smooth spirals, their interstices without secondary riblets.
Lenomyrmex inusitatus is a Neotropical species of ant in the subfamily Myrmicinae. The worker of Lenomyrmex inusitatus is distinguished from other Lenomyrmex workers by smooth and shiny mesosoma with well-developed propodeal spines and by the foveolate-striate sculpture covering all the dorsal surface of its head. L. inusitatus has an unusual distribution since it is the single Lenomyrmex species recorded east of the Andes.
The cap is 4.5–16 (18) cm wide, convex, and becomes broadly convex to flat in age. It is bright yellow or yellow-orange, usually more orange or reddish orange towards the disc, and fading to pale yellow. The volva is distributed over the cap as cream to pale tan warts; it is otherwise smooth and sticky when wet. The margin becomes slightly striate in age.
The size of the shell varies between 40 mm and 57 mm. The spire is concavely elevated, tuberculate and closely striate. It is nebulously painted with orange-brown, chestnut or chocolate and white, the latter forming usually an interrupted and irregular central band, besides being miscellaneously disposed on other parts of the surface. It is encircled by close narrow brown lines, which are sometimes slightly raised.
The spire is conic. The five whorls are a little tumid below each suture, and with a narrow ledge or margin, marked off by an impressed line, above each suture. This peripheral ledge gives the body whorl a rather prominent keel. The surface is polished, but shows quite prominent, spaced, impressed growth lines, and under a lens is all over very densely minutely spirally striate.
The thorax is almost identical, but the clear space between the metapleural striate area and propodeal spiracles is either a narrow crease or not present. The side portions of the petiole are punctate. The sides of the postpetiole are opaque with punctures present, but no irregular roughening is seen. The anterior of the dorsum is shagreen, and the middle and rear regions bear transverse puncto-striae.
Psilocybe strictipes has a farinaceous smell and taste. Pleurocystidia are absent and its lageniform cheilocystidia are 21-45 by 7-10 µm. The cap is 5 to 30 mm across, conic to campanulate to convex, smooth, and translucent-striate near the margin, often with a low umbo. It is walnut brown to dark rusty brown, with a smooth surface and a separable gelatinous pellicle.
The stipe is 2.0-7.0 cm long, 1.5-3.0 cm thick, and more or less equal except for a bulbous base. In addition, it has a narrow, cottony central core. The surface of the apex is palled and finely striate, while the lower stipe can vary from glabrous to sparsely covered with whitish fibrils, occasionally sheathed with cottony-floccose veil remnants. Like the cap, it yellows.
Southward the color becomes deeper, of a salmon hue, and the sculpture finer. The surface is spirally traversed by unequal cord-like lirae, separated by sharply crispate- striate interspaces, as wide or wider than the ridges. The latter are nearly smooth or show traces of the oblique striation. Upon the last 1½ whorls there is usually a spiral thread in the inter-liral spaces.
The interstices are slightly broader than the riblets. They are crossed by spiral threads,4 fine and close together on the shoulder, 1 on the carina of the whorl, and 3 below it, the uppermost of these at some distance from the keel. The crossing-points are produced into small oval gemmules. The base is spirally striate, all the striae in front of the aperture being smooth.
Herpolitha is a monotypic genus of mushroom corals in the family Fungiidae. The only member of the genus is Herpolitha limax, commonly known as the tongue, slipper, mole or striate boomerang coral. It is a free-living species and is native to reefs and lagoons in the Indo-Pacific region. The International Union for Conservation of Nature has assessed this coral as being of "least concern".
Its brassy colour, smaller size, and more finely and closely punctate- striate elytra distinguish it from its ally, P. chrysocephala, which is also found on Lundy. P. luridipennis is sometimes called the "bronze Lundy cabbage flea beetle" to differentiate it from another beetle found on the Lundy cabbage. This latter beetle, the "blue Lundy cabbage flea beetle", is a short- winged form of the widespread P. napi.
The body whorl is convex above, and slightly depressed beneath the suture, at the periphery flattened and biangulate. The base of the shell is nearly flat, delicately spirally striate, around the umbilicus encircled with a shallow groove. The umbilicus is white, deep, surrounded by a whitish callus forming a faint tooth at the base of the columella. It is bordered by a shallow sulcus on the whorl.
The slender stems are 30–100 mm tall and 3–10 mm wide, white striate above a substantial membranous ring and slightly scaly and greyish below. Flesh is thin and white and the lamellae are adnate, broad and very distant. Cystidia are thin-walled cylindric or utriform. Spore print is white, they are smooth and subglobose in shape and very thickwalled at 13–18×12–15 µm.
Trachelomonas is a genus of swimming, free-living euglenoids characterized by the presence of a shell-like covering called a lorica. Details of lorica structure determine the classification of distinct species in the genus. The lorica can exist in spherical, elliptical, cylindrical, and pyriform (pear- shaped) forms. The lorica surface can be smooth, punctuate or striate and range from hyaline, to yellow, or brown.
The pronotum is significantly narrower than the elytra and with lateral margins slightly crenulated; the prosternal processes are broad and flat, rounded to truncate at the apex; the elytra are vaguely striate and have a series of short spines of unknown function.Kavanaugh, D. H. (1986) A systematic review of amphizoid beetles (Amphizoidae: Coleoptera) and their phylogenetic relationships to other Adephaga. Proceedings of the California Academy of Sciences, vol.
It is sculptured with oblique longitudinal folds (11 on the penultimate whorl) which stop abruptly at the shoulder and gradually decrease below. The spirals are rather spaced, coarse and unequal, alternating in size, absent on the concave upper surface of the whorls. The surface between lirae and over the concave anal fasciole is finely spirally striate. The aperture is subrhombic, narrowed below, slightly over one-third the shell's length.
The anal fasciole is not spirally striate. The axial sculpture consists of (on the body whorl about 10) sharp- edged ribs, with wider interspaces, compressed and arcuate on the anal fasciole, nearly vertical elsewhere and extending over the whole whorl, but not continuous over the spire. The incremental lines are inconspicuous. The aperture is rather wide and short with a deep rounded anal sulcus and a prominent subsutural callosity.
The size of the shell varies between 31 mm and 130 mm. The low shell has a distantly but distinctly tuberculated spire, and direct sides, slightly striate at the base. Its color is yellowish brown, orange or pink, sometimes without markings, but usually with irregular longitudinal chestnut or chocolate striations most of which are continuous from spire to base. They vary from fine and close to heavier and more distant markings.
Orientation columns are located in the primary visual cortex also known as the striate cortex. These orientation columns are not cylindrical in shape as the word column implies but are flat slabs that are parallel to each other. The slabs are perpendicular to the surface of the visual cortex and are lined up similar to slices of bread. These neurons are highly discriminatory for visual orientations and their motion.
In 1958, David Hubel and Torsten Wiesel discovered cells in the visual cortex that had orientation selectivity. This was found through an experiment by giving a cat specific visual stimuli and measuring the corresponding excitation of the neurons in striate cortex (V1). The experimental set up was of a slide projector, a cat, electrodes, and an electrode monitor. They discovered this orientation selectivity when changing slides on the projector.
Ordered Arrangement of Orientation Columns in Monkeys Lacking Visual Experience. [Article]. Journal of Comparative Neurology, 158, 307-318. Also if the visual environment is confined to only vertical or horizontal lines during this critical period the distribution of the preferred orientation of cells in the striate cortex become abnormal. This is probably due to cells maturing their preferred orientation to that of the most common type of visual stimulus.
Acroglochin persicarioides is an erect glabrous annual herb, 30–80 cm tall. The sparsely branched stems are ribbed and striate, green or purplish. The alternate leaves (up to 6 cm long) are long petiolate, their simple leaf blades are ovate to deltoid with irregularly and coarsely toothed margins. The inflorescences are numerous branched cymes in the axils of almost all leaves, erect-spreading, contracted, with short sterile branches ending needle-like.
M. adscendens shown here. The holotype of Protomycena is a single fruit body without any associated structures, preserved in a piece of clear light yellow polished amber approximately wide. The pileus is in diameter and has a convex shape, sporting a raised central region (an umbo). The pale flesh appears yellowish in the amber, and is smooth and glossy, changing to striate and slightly translucent towards the margin.
The height of the shell attains 9 mm, its diameter 12 mm. A pale brownish-pink-coloured Clanculus, with obscure pink spotting basally. It is depressedly conical, narrowly umbilicate, the umbilical region coarsely crenate. It is six- or seven- whorled, the three lowest whorls possessing, firstly, three rows of close spiral fine granules followed by others which have a fine spiral line dividing them, the interstices being very finely obliquely striate.
Attaching by adventitious roots, its stems are up to 10 cm in diameter, are occasionally armed with stinging hairs and exude copious and clear potable sap when cut. Bark is grey to brownish-black and longitudinally striate with large leaf scars on young branches. Pith is spongy, or stems are hollow in centre. Leaves are simple and with drip tips, elliptic to ovate with entire margins, and spirally arranged.
The folds number about thirty-six on the body whorl and terminate on the periphery in nodules (or spines in the young,) generally intersected about the middle by two to four spiral impressed lines. The periphery is angled, more or less swollen. The base of the shell is nearly flat, more or less sharply radiately striate, and spirally lirate. The frequently nodulose lirae number about six, or sometimes more.
The cap is 4–13 cm wide, hemispheric to convex when young, becoming plano-convex to plano-depressed in age. It is pinkish-melon-colored to peach-orange, sometimes pastel red towards the disc. The cap is slightly appendiculate. The volva is distributed over the cap as thin pale yellowish to pale tannish warts; it is otherwise smooth and subviscid, and the margin becomes slightly to moderately striate in age.
The surface of the shell is finely spirally striate, the striae about 8 on the body whorl, with a couple of stronger ribs at the periphery, which are visible above the suture on the spire whorls. The short spire is conic, acute, with its lateral outlines rectilinear. The 7–8 whorls are flat, the last one acutely carinated, and flat beneath. The oblique aperture is rhomboidal, smooth and nacreous within.
The cap can grow to in diameter, and is convex at first becoming flattened with age, sometimes developing a depressed centre. The cap has a slightly curved margin and is often striate with the gills visible through its thin structure. The centre is dark brown and scaly. The rest of the cap is yellowish-brown to brown, paler when it is dry and darker when it is moist.
The inflorescence is a dense raceme, almost globose, up to 14 mm diameter, on a peduncle about 1 cm long in the axils of most upper leaves. Corolla or petals are white, irregularly five- lobed, and about 5 mm long. The calyx, 4 mm long, also has five narrow, finely barbed lobes. Seeds are ovoid, up to 1 mm long, dark brown to black, obscurely striate, with a conspicuous scar.
The 5 to 5½ whorls are nearly planulate, but the upper margin of each whorl is prominent and projecting beyond the periphery of the preceding. The body whorl is carinated at the periphery. The sculpture above consists of spiral lirae, about 5 to 8 on each whorl, cut into close oblique beads. The interstices are obliquely finely striate, one or two of the broader ones usually with a central riblet.
The stipe is 5–12 cm long, 2–3 mm thick, hollow, and vertically striate. It is blackish towards the base, greyish towards the apex, and pallid to whitish fibrils run the length of the stipe. The stipe is equal to slightly swollen at the base and lacks a partial veil. Panaeolus tropicalis spores are dark violet to jet black, ellipsoid, and 10.5–12.0 x 7–9 µm.
The spreading or compact, intricately branched shrub typically grows to a height of . It has striate and ribbed branches that are covered in a fine, white powdery coating with many short and spreading branchlets that are a quite spiny and often without phyllodes. Like most species it has phyllodes rather than true leaves. The ascending to erect phyllodes have a narrowly oblong shape and are usually straight or shallowly sigmoid.
Mutations in this gene are the cause of several cardiomyopathies, including dilated cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy. Mutations in DSP have also been associated with striate palmoplantar keratoderma. Carvajal syndrome results from an autosomal recessive mutation of a frameshift (7901delG) in DSP that results in a combination of above conditions, including dilated cardiomyopathy, keratoderma and woolly hair. Patients with Carvajal syndrome often suffer from heart failure in teenage years.
The periphery is acutely carinated, bearing numerous short compressed triangular radiating spines. The flat base of the shell is densely radiateiy lamellose-striate, with a strong rib revolving midway between the periphery and the center The aperture is oblique, pearly white within, transversely ovate, deeply channelled at the periphery. The columellar region is white, strongly bicostate, deeply excavated at the position of the umbilicus. The parietal callus is not much extended.
The sculpture consists of spiral series of closely set rounded granules, the series or cinguli a little separated on the upper surface, closer beneath. These number 17 or 18 upon the body whorl, the 7th being upon the periphery, just as in Clanculus clanguloides. The interstices between lirae are finely obliquely and spirally striate, the spiral striae often a little difficult to distinguish. This gives the interstices at times a granulate appearance under the lens.
Snails in the genus Vertigo have no oral tentacles, thus they have only one pair of tentacles. The jaw is arched; the ends squarely truncated; the anterior surface striate; the cutting edge with a median projection. The radula has a central tooth that is almost square, tricuspid, as large as or larger than the lateral teeth, which are similar, narrower, and bi- or tricuspid. The marginal teeth are low, wide and serrated.
Bruising or cutting results in a red stain after a minute. The surface of the stipe is barely striate above the annulus, and smooth below except for fragments of the universal veil. During development the veils rupture and form an upper veil (partial veil), which initially hangs from the edge of the cap, and a lower veil. As the partial veil disintegrates, it often leaves fragments 2–3 mm in size attached to the margin.
The about 6 whorls are subplanulate, but with a slightly salient central carina above. They are spirally finely granose-lirate, the lirae narrow, close, about 8 to 12 in number on the upper surface of the body whorl, the 5th forming a slightly projecting carina. The base is finely lirate, the lirae granose, about 15, subequal, or sometimes alternately smaller with the radiately striate interstices. The aperture is rather large and subrhomboidal.
Using such low currents in combination with visual psychophysics, he was able to estimate the size, contrast, and color of phosphenes evoked from the visual cortex of monkeys.P.H. Schiller and E.J. Tehovnik, Visual prosthesis. (2008) Perception, 37, 1529-1559. P.H. Schiller, W.M. Slocum, M.C. Kwak, G.L. Kendall and E.J. Tehovnik EJ, New methods devised specify the size and color of the spots monkeys see when striate cortex (area V1) is electrically stimulated.
V1 is often also called striate cortex because it can be identified by a large stripe of myelin, the Stria of Gennari. Visually driven regions outside V1 are called extrastriate cortex. There are many extrastriate regions, and these are specialized for different visual tasks, such as visuospatial processing, color differentiation, and motion perception. The name derives from the overlying occipital bone, which is named from the Latin ob, behind, and caput, the head.
The branched, monoecious inflorescence has a 12–30 cm long prophyll. The inflorescence develops within a woody, glabrous (hairless) spathe which eventually grows 70–105 cm in total length, and has a swollen portion at the end 61–81 cm long and 6–13 cm wide. This swollen portion is often coloured purplish and the whole spathe may sometimes be smooth or striate. The inflorescence has a 35–60 cm long peduncle.
This is also referred to as "striate cortex", with other cortical visual regions referred to collectively as "extrastriate cortex". It is at this stage that color processing becomes much more complicated. In V1 the simple three-color segregation begins to break down. Many cells in V1 respond to some parts of the spectrum better than others, but this "color tuning" is often different depending on the adaptation state of the visual system.
The genus was first described by Italian doctor and naturalist Carlo Vittadini in 1831. for hypogeous (below-ground) gasteromycetes with chambers exposed to the surface and lined with a spore- bearing hymenium, a basal rhizomorph, and ovoid-fusiform, striate-grooved spores. Vittadini's original concept was based on two species he collected in Italy, Gauteria morchellaeformis and Gautieria graveolens. In 1918, Zeller and Dodge examined various dried herbarium collections of Gautieria, and recognized five species.
The perianth is undifferentiated (perigonium) and biseriate (two whorled), formed from six tepals arranged into two separate whorls of three parts (trimerous) each, although Scoliopus has only three petals, free from the other parts, but overlapping. The tepals are usually petaloid (petal like) and apotepalous (free) with lines (striate) or marks in other colors or shades. The perianth is either homochlamydeous (all tepals equal, e.g. Fritillaria) or dichlamydeous (two separate and different whorls, e.g.
Striate arteries or ganglionic arteries arise from the middle cerebral artery and supply deep structures in the cerebrum, including the internal capsule and reticular formation. Strokes in these vessels are common and can cause extensive damage. This is because emboli are carried up the carotid and tend to be swept into the MCA, sometimes called the "artery of stroke", and are prone to getting stuck at this branch point in the lateral sulcus.
The cap is initially ovoid in shape, but in maturity becomes convex and eventually flattened. Orange to bright yellow-orange in color, it reaches diameters of . Young specimens are covered with chrome yellow warts that may be easily rubbed off or washed away with rain.Closeup of cap surface The cap surface is smooth and sticky (viscid) beneath the warts; the edge of the cap is striate, reflecting the arrangement of the gills underneath.
The body whorl is encircled by three prominent, equidistant carinae, one subsutural, composed of rounded or radiating knobs followed by two or three beaded lirulae, two at the periphery, prominently beaded, with a beaded riblet between them. The base of the shell is encircled by 5 more or less beaded, equal lirae. The entire surface is microscopically obliquely striate, and in some places decussated by microscopic spiral striae. The oblique aperture is rounded-quadrate.
The 6-7 whorls are, sharply carinated. Their upper surface is concave, longitudinally more or less finely and irregularly plicate below the sutures; coarsely plicate on the lower half of the whorls. The folds terminate in short nodes at the periphery, twelve to sixteen in number on the body whorl, and also scalloping the sutures. The base of the shell is flat, somewhat depressed around the middle, finely concentrically lirate and radiately striate.
The stipe measures long by wide, and is either equal in width throughout, or tapers on either end. Initially stuffed with a cottony mycelium when young, it hollows in maturity. Colored similar to the cap, the stipe surface ranges from smooth to canescent (covered with a whitish-grey bloom) when wet, to fibrillose-striate when dry. The stipe base features a dense mass of whitish rhizomorphs embedded with needles and other forest debris.
Receptive field profiles registered by cell recordings have shown that mammalian vision has developed receptive fields tuned to different sizes and orientations in the image domain as well as to different image velocities in space-time.D. Hubel and T. N. Wiesel (1959) "Receptive field of single neurons in the cat’s striate cortex", J Physiol 147, 226–238.D. Hubel and T. N. Wiesel (2005) Brain and Visual Perception: The Story of a 25-Year Collaboration. Oxford University Press.
The shell is somewhat subquadrately oval, thin, diaphanous, close, finely striate concentrically, whitish horny, or slightly tinted with fuscous patches near the umbones, and covered with numerous granular points, which are finer and more crowded on the umbones, where the concentric striation is less evident. The shell is anteriorly rather short and subangulate, posteriorly a little truncate. The hinge is with well-developed lateral teeth in both valves, 1-1/1-1. The cardinal teeth is small 2/2.
Close-up on flowers of Campanula spicata Campanula spicata has its overwintering buds situated just below the soil surface (hemicryptophyte) and a stalk growing directly from the ground (scapose). This plant reaches on average in height. The stem is erect, striate and hairy, the basal leaves are petiolated, narrowly lanceolate, with toothed and wavy margins, the cauline leaves are smaller, acuminate and semiamplexicaul. The numerous flowers are arranged in a more or less dense and long spikes.
The whole base is covered with rather regular, riblike striae and very fine microscopic ones, visible also on the upper part of the shell. The large umbilicus occupies from the base of the columella to the opposite side, about 2/5 of the diameter of the shell It is funnel-shaped, and pervious. Its wall is spirally striate, with a single, spiral, beaded rib and radiating plicae. The thin aperture is rhombic, probably not quite developed.
Pholiotina cyanopus is a small saprotrophic mushroom with a conic to broadly convex cap which is smooth and colored ocher to cinnamon brown. It is usually less than 25 mm across and the margin is striate, often with fibrous remnants of the partial veil. The gills are adnate and close, colored cinnamon brown with whitish edges near the margin, darkening in age. The spores are cinnamon brown, smooth and ellipsoid with a germ pore, measuring 8 × 5 micrometers.
The sculpture consists of slightly curved obliquely longitudinal ribs, 11 on the body whorl, the last one, behind the lip, much larger. These are crossed by spaced spiral threads, with, smaller threads between them, the intervals still more finely striate spirally. The shell contains 5 whorls (the embryonic ones broken off), strongly angular near the middle, flattened and sloping above the angle, contracting below it. The body whorl is similarly angular, convex below the angle, contracted near the base.
It is mottled near the periphery with whitish fiammules. The white nucleus is translucent and tilted obliquely. The sculpture on the subsequent four or five whorls, of five (5) granular, spiral ridges, separated only by narrow incised lines, with a more conspicuous ridge just above the suture. Subsequently, the ridges become flattened, wider and more or less spirally striate on their tops, while the original five incised lines retain a darker color than the rest of the surface.
The margin is non-striate (without any grooves), and appendiculate (with partial veil remnants hanging along the cap margin). The gills are free from attachment to the stem, crowded together, moderately broad, and yellowish- white to pale yellow. Interspersed among the gills are short gills (lamellulae) that do not extend completely to the stem; they are somewhat truncated (abruptly terminated) to attenuated (tapering gradually). The stem is long and wide, and decreases slightly in thickness near the apex.
The color of the shell is whitish or yellowish, finely tessellated or articulated with reddish brown The tessellations are formed by the disintegration of narrow radiating stripes, which are on the base frequently continuous. The base of the shell is nearly flat, with seven or eight concentric close fine lines, which are crenulated in a peculiarly irregular manner by distinct short oblique impressed marks. The interstices are finely radiately striate. The subrhomboidal aperture is smooth within.
On the body whorl there are three spiral ribs in front of the aperture, usually less distinct as they approach the outer lip, and with one or two threads in the interspaces. Anterior to this are ten or eleven small spirals, somewhat irregular in size. Above the sinus are seven or eight threads, two of which are slightly stronger, and in some examples form small ribs. The whorls are transversely striate with growth lines, oblique on the sinus area.
Such a separation of positive and negative components is totally compatible with retinal physiology and is one possible function for the known pair of midget bipolar channels for each receptor.Computer Vision: A unified, biologically-inspired approach by Ian Overington Pages 45-46 Published by Elsevier North Holland 1992 The basic evidence for orientation sensing in human vision is that it appears to be carried out (in Area 17 of the striate cortex) by banks of neurones at fairly widely spaced orientations.Plasticity of ocular dominance columns in monkey striate cortex by D.H. Hubel, T.N Wiesel and S. LeVay, Philosophical Transactions of the Royal Society B, Volume 278, Page 377, 1977 The neurones as measured have characteristically elliptical receptive fields.Computer Vision: A unified, biologically-inspired approach by Ian Overington Pages 46 to 49 Published by Elsevier North Holland 1992 However, both the actual interval between the orientations and the exact form & aspect ratio of the elliptical fields is open to question, but at the same time the said receptive fields have to have been compounded with the midget receptive fields at the retina.
Psilocybe weilii caps range from (2)3 to 6(8.5) cm in diameter and are obtusely conic to convex to campanulate. The margin is incurved or inrolled when young, becoming irregularly lobulated then straight with age. Psilocybe weilii are subumbonate, hygrophanous, glabrous, and subviscid when moist from the separable gelatinous pellicle. It is translucent-striate at the margin, and purple brown or chestnut brown to dark brown, fading to buff or straw yellow as it dries, with the center remaining blackish brown.
The cap surface is smooth, faintly translucent- striate when moist, at first pruinose but soon naked. The color is red when young, soon becoming yellowish toward the margin, and slowly fading to bright orange-yellow. The flesh is thin, brittle, yellow, and has no distinctive odor or taste. The gills are adnate (with gills broadly attached to the stem, slightly above the bottom of the gill, with most of the gill fused to the stem) or slightly rounded next to the stem.
The about six whorls are somewhat convex. The upper surface of each whorl shows usually four or five spiral closely granose lirae, in the interstices between which sharp microscopic oblique and spiral striae are visible under a lens. The body whorl is carinated at the periphery, usually with six lirae on the upper surface, convex beneath, concentrically lirate, the lime very narrow, feebly granose or nearly smooth, separated by wide lightly obliquely striate interspaces, the inner lirae closer. The aperture is rhomboidal.
They contain (1) 3-5 herbaceous, unkeeled perianth segments, connate only at base or nearly to the middle, sometimes missing; a circle of 1-5 stamens; and an ovary with 2-4 stigmas. In fruit, the perianth becomes either succulent or dry and hard. The pericarp is membranous and usually adhering to the vertically orientated, broadly ovate to orbicular seed. The seed coat is dark brown to black, its surface can be dull, almost smooth, slightly striate, rugulose, or reticulate.
However, Hubel and Wiesel noticed that rectangular bars of light were more effective stimuli (i.e. more natural stimuli) than circular spots of light, as long as the orientation was adjusted to the correct angle appropriate for each ganglion cell. These so- called simple cells were later called bar detectors or edge detectors. While comparing the receptive fields of neurons in the cat striate cortex with the concentric "on" and "off" receptive fields identified in cat ganglion cells by Kuffler et al.
The about 7 whorls are concave below the sutures, convex and swollen at the periphery and on the lower edge of each whorl of the spire. The whole surface is finely spirally lirate, the lirae about as wide as the interstices, which are delicately obliquely striate. The aperture is oval-quadrate, iridescent within and measures less than half the length of shell. The peristome is edged by a row of crimson dots, with a porcellaneous internal thickening which is iinely crenulate.
The size of an adult shell varies between 40 mm and 110 mm. The spire is striate, channeled, concavely elevated, sharp-pointed. It has a sharp shoulder angle. The lower part of body whorl is punctured and grooved The color of the shell is orange-brown to chocolate, thickly covered with large and small subtriangular white spots, which by their varied disposition sometimes form a white central band, or dark bands above and below the center, the latter occasionally bearing articulated revolving lines.
The aperture is quite oblique, rounded-ovate, angular above, broadly rounded below, with a thin iridescent layer of nacre within. The outer, basal and columellar margins are rather thin, curved, the latter joined to the upper margin by a thin white parietal callous. The narrow umbilicus is not bounded by an angle.Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia This dull whitish little shell may be known by its finely striate surface, narrow umbilicus, short spire and globose-turbinate form.
The staminate flowers are solitary borne, on second and third order branches, subtended by a tiny, tubular, triangular bract and a two keeled bracteole. The tubular calyx is proximally striate, divided into three triangular lobes; the corolla is divided nearly to the base into three lobes. The six stamen are borne at the base of the corolla with fleshy, elongated filaments, inflexed at the tip, with oblong, medifixed anthers. The pollen is elliptic, diporate with rugulate to reticulate, tectate exine.
The optic radiation (also known as the geniculocalcarine tract, the geniculostriate pathway, and posterior thalamic radiation) are axons from the neurons in the lateral geniculate nucleus to the primary visual cortex. The optic radiation receives blood through deep branches of the middle cerebral artery and posterior cerebral artery. They carry visual information through two divisions (called upper and lower division) to the visual cortex (also called striate cortex) along the calcarine fissure. There is one such tract on each side of the brain.
The visual cortex of the brain is the area of the cerebral cortex that processes visual information. It is located in the occipital lobe. Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex. The area of the visual cortex that receives the sensory input from the lateral geniculate nucleus is the primary visual cortex, also known as visual area 1 (V1), Brodmann area 17, or the striate cortex.
The extrastriate cortex is the region of the occipital cortex of the mammalian brain located next to the primary visual cortex, which is also named striate cortex because of its striped appearance in the microscope. The extrastriate cortex encompasses multiple functional areas, including V3, V4, V5/MT, which is sensitive to motion,Guy A. Orban. Higher Order Visual Processing in Macaque Extrastriate Cortex. Physiol Rev January 1, 2008 88:(1) 59-89; or the extrastriate body area (EBA) used in the perception of human bodies.
Basidiocarps are agaricoid, up to 100 mm (4 in) tall, the cap convex at first and remaining convex or becoming flat when expanded, up to 50 mm (2 in) across. The cap surface is very viscid when damp, striate at the margin, and pale greyish brown. The lamellae (gills) are whitish to pale cap- coloured and more or less decurrent (widely attached to and running down the stipe). The stipe (stem) is very viscid when damp, smooth, cylindrical or compressed, and grey to cap-coloured.
In a 1995 experiment, researchers attempted to show that monkeys with lesions in or even wholly removed striate cortexes also experienced blindsight. To study this, they had the monkeys complete tasks similar to those commonly used on human subjects. The monkeys were placed in front of a monitor and taught to indicate whether a stationary object or nothing was present in their visual field when a tone was played. Then the monkeys performed the same task except the stationary objects were presented outside of their visual field.
In a series of now classic studies Schiller characterized the functions of two sets of parallel pathways in the visual system: The On- and Off- pathways and the midget and parasol pathways. By administering 2-amino-4-phosphono-butyrate (APB) to the eye, he was able to inactivate the ON-retinal pathway reversibly and demonstrate that the On- and Off-pathways remain segregated from the retina to the striate cortex.P.H. Schiller, Central connections of the retinal ON and OFF pathways. (1982) Nature, 297, 580-583.
They often show a few spiral rows of beads, finely, very obliquely striate, but all this surface sculpture is often obsolescent. The periphery of the whorls and at the sutures is armed with distant strong radiating solid knobs, about six to ten on the body whorl. The base of the shell is flat, smooth, partly polished, with an appearance of obsolete concentric lirae about. the central portion, white, or with a zone of blue or of green or both colors surrounding the axial tract.
The length of the holotype attains (the early whorls lost) 26.5 mm, its diameter 8.3 mm; whorls remaining. (Original description) This species is very similar to Carinodrillia elocata, but it is more slender with a longer anterior canal and a deeper posterior sinus. The anal fasciole and the spaces between the spiral ridges are distinctly striate spirally, with in each interval about 6 striae. There are seven broad, rounded axial folds on the penultimate whorl and on the body whorl, weakening on the anal fasciole.
The length of the shell varies between 15 mm and 25 mm. The solid shell has a conical shape with nearly straight outlines and is false- umbilicate. The sculpture of the upper surface consists of 5 series to each whorl of rounded bead-like granules, between which are visible numerous very minute spiral striae, in the interstices of which oblique incremental striae are prominently shown under a lens. The base of the shell is concentrically striate with unequal striae that disappear toward the outer edge.
Flowers of Beta vulgaris Beta vulgaris is an herbaceous biennial or, rarely, perennial plant up to 120 cm (rarely 200 cm) height; cultivated forms are mostly biennial. The roots of cultivated forms are dark red, white, or yellow and moderately to strongly swollen and fleshy (subsp. vulgaris); or brown, fibrous, sometimes swollen and woody in the wild subspecies. The stems grow erect or, in the wild forms, often procumbent; they are simple or branched in the upper part, and their surface is ribbed and striate.
The trunks are rough and solitary natured, and reach over 10 m at 20 cm wide, usually covered in old leaf bases. The sheath is tubular, splitting adaxially, striate, and covered in white and brown tomentum. The petiole is short, deeply channeled, flattened below, with armed margins and similar tomentum; the rachis is slightly arched, leaflets regular or grouped, in one or several planes with one fold. The undersides are glaucous, the apex is irregularly bifid, the midrib is prominent and the veinlets are evident.
The larger pistillate flowers are borne in dyads, similarly subtended by a triangular bract, and accompanied by a sterile staminate flower and two, two keeled bracteoles. The sterile staminate flower is similar to the fertile but is slightly contorted with empty anthers. The pistillate has a striate, cup shaped calyx with triangular, valvate lobes, and the corolla splits to the base into similar triangular segments. There are six epipetalous staminodes, with triocular, triovulate, scaly, ovoid gynoecium and three fleshy, divergent, rugose stigmas, attached at the base.
Though it does not necessarily require fertilizer, the grass responds well to supplemental nitrogen. Good companion plants include legumes such as three-flower beggarweed (Desmodium triflorum), glycines (Glycine spp.), pinto peanut (Arachis pintoi), Australian jointvetch (Aeschynomene falcata), Brazilian stylo (Stylosanthes guianensis), lotononis (Lotononis bainesii), round-leaf cassia (Chamaecrista rotundifolia), and white clover (Trifolium repens). Pathogens seen in this grass include grey mould and the digitaria striate mosaic virus, a mastrevirus of the family Geminiviridae which is transmitted by the leafhopper Nesoclutha pallida.Lapierra, H. and P. A. Signoret.
Nicholas Humphrey was educated at Westminster School (1956–61) and Trinity College, Cambridge (1961–67). His doctoral research at Cambridge, supervised by Lawrence Weiskrantz, was on the neuropsychology of vision in primates. He made the first single cell recordings from the superior colliculus of monkeys, and discovered the existence of a previously unsuspected capacity for vision after total lesions of the striate cortex (a capacity which, when it was later confirmed in human beings, came to be called "blindsight"). On moving to Oxford, he turned his attention to evolutionary aesthetics.
Pyramidal cells in the visual cortex (or striate cortex) of the cuneus, project to extrastriate cortices (BA 18,19). The mid-level visual processing that occurs in the extrastriate projection fields of the cuneus are modulated by extraretinal effects, like attention, working memory, and reward expectation. In addition to its traditional role as a site for basic visual processing, gray matter volume in the cuneus is associated with better inhibitory control in bipolar depression patients. Pathologic gamblers have higher activity in the dorsal visual processing stream including the cuneus relative to controls.
The young stems are completely coloured a pale green, later becoming whitish to cream-coloured, and are terete or delicately striate in cross-section. The larger branches at the top of the bush are often erect or ascending, whereas the lower branches are more prostrate on the ground. The stems end in a bracteate inflorescence, this is also variable in form: it can be either loose or densely flowered, and the floral spike can be either short or long. The very ends of the inflorescences are often flexuose.
Desmosomes are involved in cell-cell adhesion, and are particularly important for the integrity of heart and skin tissue. Because of this, desmocollin gene mutations can affect the adhesion of cells that undergo mechanical stress, notably cardiomyocytes and keratinocytes. Genetic disorders associated with desmocollin gene mutations include Carvajal syndrome, striate palmoplantar keratoderma, Naxos disease, and arrhythmogenic right ventricular cardiomyopathy. There is also evidence that autoimmunity against desmosomal cadherins contributes to cardiac inflammation associated with arrhythmogenic right ventricular cardiomyopathy, and that anti-desmosomal cadherin antibodies may represent new therapeutic targets.
Young fruit bodies are oval or egg-shaped. The cap of C. variegata is thin, initially oval-shaped then bell-shaped, and then flattened with the margin turned upward; it reaches diameters of up to . When young, the surface of the cap is covered with a woolly whitish or yellowish veil that breaks up into short-lived flakes or scales; this process reveals the radially striate (grooved) gray to grayish- brown cap surface. The gills are broad, thin, crowded closely together, and free from attachment to the stem.
The act of changing the slides produced a faint shadow line across the projector, and excited the neuron they were measuring. At the time of this experiment it was not conclusive that these orientation selective cells were in a "columnar" structure but the possibility of this structure was considered by research conducted by Vernon Mountcastle in 1956 about the topographic properties of the somatosensory system. Hubel, D. H., & Wiesel, T. N. (1959). Receptive Fields of Single Neurones in the Cat's Striate Cortex. [Article]. Journal of Physiology, 148, 574-591.
Ocular dominance columns are stripes of neurons in the visual cortex of certain mammals (including humans) that respond preferentially to input from one eye or the other. The columns span multiple cortical layers, and are laid out in a striped pattern across the surface of the striate cortex (V1). The stripes lie perpendicular to the orientation columns. Ocular dominance columns were important in early studies of cortical plasticity, as it was found that monocular deprivation causes the columns to degrade, with the non-deprived eye assuming control of more of the cortical cells.
The bioluminescent fungus M. lux-coeli is another allied species, but it has smaller spores (8.5–12 by 6.5–9 µm) and its cystidia are more lobed. Another similar "bleeding" Mycena is M. haematopus, which usually grows in clusters on rotting wood. In his original protologue, Peck mentioned that he considered the species closely related to M. rubromarginata, but could be distinguished by its darker color and "non-hygrophanous striate pileus." Microscopically, M. rubromarginata differs from M. purpureofusca in having abundant clamp connections and narrow necks on the cheilocystidia.
The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. The primary visual cortex is Brodmann area 17, commonly called V1 (visual one). Human V1 is located on the medial side of the occipital lobe within the calcarine sulcus; the full extent of V1 often continues onto the posterior pole of the occipital lobe. V1 is often also called striate cortex because it can be identified by a large stripe of myelin, the Stria of Gennari.
The periphery of the body whorl is sometimes articulated with white, and the base of the shell is either unicolored dark, or finely dotted with white. The shell contains 10 whorls, the apical one or two convex and smooth, the following flat, finely spirally striate (about 14 striae on the penultimate whorl of a large specimen). The body whorl is convex at the periphery, angulated there in specimens not completely adult, and convex beneath, with 10-12 concentric lirulae there. The entire surface contains fine lines of growth.
Binocular neurons in both the medial superior temporal area and dorsal extrastriate area (V5/MT) respond to surface depth sparation. On one hand, the anticorrelated response of the binocular neurons in the striate cortex (V1), the prestriate cortex (V2), dorsal extrastriate area (V5/MT), and medial superior temporal area, all show similar responses. On the other hand, binocular neurons in the ventral extrastriate area (V4) show weaker anticorrelated responses in comparison to the other areas. Finally, areas in the anterior inferior temporal cortex do not show any anticorrelated response.
A. exitialis has been misidentified as the European species A. verna, shown here. The cap is in diameter, initially egg-shaped, then convex but flattening with age, and sometimes slightly depressed at the center. The cap surface is smooth, white, but cream-colored in the center. The margin (cap edge) is non-striate, non-appendiculate (without any partial veil remnants hanging along the cap margin); the flesh white. The gills are free from attachment to the stem, white to whitish, crowded closely together, and up to 5 mm in height.
In their first paper in 1959, Hubel and Wiesel took recordings from single cells in the striate cortex of lightly anesthetized cats. The retinas of the cats were stimulated either individually or simultaneously with spots of light of various sizes and shapes. From the analysis of these recordings, Hubel and Wiesel identified orientation- selective cells in the cat's visual cortex and generated a map of the receptive field of cortical cells. At the time, circular spots of light were used as stimuli in studies of the visual cortex.
Plants annual, 10–60(–80) cm. Taproot 2–3 mm thick. Stem solitary, striate, scabrous. Lower petioles 3–8 cm; blade ovate-lanceolate, 3–8 × 2–5 cm, 2–3-pinnate; ultimate segments linear to linear-lanceolate, 3–10 × 1–1.5 mm, veins and margins scabrous. Umbels 2–3(–5) cm across; bracts 6–10, linear to linear-lanceolate, 2–3 mm, persistent, margins narrowly white membranous, very finely ciliate; rays 8–20(–30), 5–20 mm, unequal; bracteoles 5–9, linear, nearly equal pedicels, margins ciliate; umbellules 15–20-flowered; pedicels 3–5 mm.
Subsequently, Kentridge, Nijboer and Heywood showed that the same was true of neurologically normal people. Kentridge has also conducted research into the neural bases of colour vision through the study of patients with cerebral achromatopsia. He has shown that such patients, despite having no conscious experience of colour, extract colour contrast signals from visual information originating in the retina. Kentridge, Heywood and Weiskrantz have furthermore shown that a patient with an extensive lesion to their striate cortex does not even extract contrast signals and responds behaviourally only to the wavelength of light.
The ornament of penultimate whorl consists of four equal and equidistant granulose lirae, and obliquely transverse raised threads. Of the body whorl, a small granulose lirais interposed between the third and fourth, anterior to the fourth are two smaller equally distant from one another, the fifth is slightly granulose, whilst the sixth, which is at the periphery, is broad and obtuse. The interspaces between the lirae are faintly spirally striate. The base has seven concentric lirae, the inner ones subgranose, the outer ones plain, with a few coincident striae in the interspaces.
Both components are related to processing of visual stimuli and are under the category of potentials called visually evoked potentials (VEPs). Both components are theorized to be evoked within the visual cortices of the brain with C1 being linked to the primary visual cortex (striate cortex) of the human brain and the P1 being linked to other visual areas (Extrastriate cortex). One of the primary distinctions between these two components is that, whereas the P1 can be modulated by attention, the C1 has been typically found to be invariable to different levels of attention.
Brain areas including the superior colliculus are important for visual processing. The pre-striate area of the visual cortex, V4, and the parietal reach regions are all also important for this. 3D Medical Animation Eye Structure However, the most important region of the brain for this type of processing would be the lateral intraparietal area, which has been studied in relation to attention and intention, as well as processing in the brain of those saccadic eye movements. The lateral intraparietal area, the LIP, is associated with attention in the visual space and saccades.
Cell adhesion in desmosomes Desmoplakin is a protein in humans that is encoded by the DSP gene. Desmoplakin is a critical component of desmosome structures in cardiac muscle and epidermal cells, which function to maintain the structural integrity at adjacent cell contacts. In cardiac muscle, desmoplakin is localized to intercalated discs which mechanically couple cardiac cells to function in a coordinated syncytial structure. Mutations in desmoplakin have been shown to play a role in dilated cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, striate palmoplantar keratoderma, Carvajal syndrome and paraneoplastic pemphigus.
The forewings are brownish ochreous, sprinkled with fuscous in a somewhat striate transverse form, the whole having a slight vinous suffusion. A fuscous spot lies at the end of the cell, and a smaller one on the cell half-way to the base. There is a slightly curved shade from the lower angle of the cell, extending to the tornus and there are five elongate blackish spots along the termen, with another in the same series at the apex, and another on the costa above it. The hindwings are pale brownish cinereous.Biol. centr.-amer. Lep.
Perceptual state "switching" in binocular rivalry has been extensively studied in electrophysiological research. Data from these studies have determined the firing rates of neurons before, during, and after which the brain has "switched" between equal strength stimuli. Here, consciousness is determined through the analysis of retinal eye movements in conjunction with neuronal firing rates. An object stimulus will eventually fade from our consciousness if the retina is continually held constant relative to the object; striate‐cortex neurons are direction selective and will only respond to motion in this scenario.
The shell is ventricose, ovate, strongly glossy, very finely striate, chestnut horn-color. The shell has 5 whorls, rather rapidly increasing, convex, the last but little higher than the penult, double as high as the next earlier whorl, a little ascending in front. Suture is slightly oblique. Aperture is quite piriform, or obliquely cordate, with 1 parietal tooth (sometimes with another punctiform one), 2 columellar teeth, the lower very small, often wanting; 2 short, high, equal, immersed teeth in the palate, bounded by a reddish-brown streak in front.
The striatum, or corpus striatum (also called the striate nucleus), is a nucleus (a cluster of neurons) in the subcortical basal ganglia of the forebrain. The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia. Functionally, the striatum coordinates multiple aspects of cognition, including both motor and action planning, decision-making, motivation, reinforcement, and reward perception. The striatum is made up of the caudate nucleus and the lentiform nucleus.
The surface is dry, covered by radially arranged wrinkles or veins, neither striate nor hygrophanous. The gills are adnexed to almost free from attachment to the stem. They are somewhat distantly spaced, with between 16 and 22 gills extending fully from the stem to the edge of the cap, in addition to one to three tiers of interspersed lamelluae (short gills that do not extend fully from the stem to the cap edge). The gill color is grey-bluish later becoming pink, and the gill edges are straight or somewhat saw-toothed, and the same color as the gill face.
CNP has been influential, not least because of its early success in explaining some previously bizarre psychiatric delusions, most notably the Capgras delusion, Fregoli delusion and other delusional misidentification syndromes. The Capgras delusion is "explained as the interruption in the covert route to face recognition, namely affective responses to familiar stimuli, localized in the dorsal route of vision from striate cortex to limbic system. According to standard molecular hypotheses, acute delusions are the result of a dysregulated activity of some neuromodulators." Additionally, the study of cognitive neuropsychiatry has shown to intersect with the study of philosophy.
The 45 species are widely distributed throughout the world and some are found in most countries, although a few exist in only one or two locales. Cyathus stercoreus is considered endangered in a number of European countries. Species of Cyathus are also known as splash cups, which refers to the fact that falling raindrops can knock the peridioles out of the open-cup fruit body. The internal and external surfaces of this cup may be ridged longitudinally (referred to as plicate or striate); this is one example of a taxonomic characteristic that has traditionally served to distinguish between species.
Overall Aphaenogaster sommerfeldti can be distinguished from the related Baltic amber species A. oligocenica in several ways. A. sommerfeldti individuals have an overall more sloped and curved mesonotum with the epinotum showing more tooth liked projections on the surface then seen in A. oligocenica. The other Baltic amber species, A. mersa, shows a more extensive amount of rugose structuring to the head, thorax, and body, with a reticulation in the structuring, while that of A. sommerfeldti is a longitudinal striate pattern. A. sommerfeldti shows a similar morphology to the living species A. subterranea from the warmer areas of southern Europe.
They are broadly and deeply depressed around the stem, of irregular lengths, bright yellow to olive-yellow to mustard- yellow, and also rapidly turn blue upon exposure. The pores are the same color as the tubes, and rapidly turn blue-green with pressure; they are angular, and there are about 0.5–1.5 pores per mm. The stem is by wide, and gradually becomes larger towards the base to 10–19 mm. The top part of the stem is cream to pink, the middle finely longitudinally striate, with the striations darkening with handling, red-lavender to brown-red, lighter with age.
These classes were called simple and complex cells, which differ in how their receptive fields respond to light and dark stimuli. Béla Julesz in 1971 used random dot stereograms to find that monocular depth cues, such as shading, are not required for stereoscopic vision. Disparity selective cells were first recorded in the striate cortex (V1) of the cat by Peter Orlebar Bishop and John Douglas Pettigrew in the late 1960s, however this discovery was unexpected and was not published until 1986. These disparity selective cells, also known as binocular neurons, were again found in the awake behaving macaque monkey in 1985.
However more recent evidence using source localization techniques such as brain electrical source analysis (BESA) in conjunction with fMRI points to the C1 being generated in the primary visual cortex of Brodmann's area 17. Clark, Fan, and Hillyard (1995) for example, using a paradigm whereby circular checkerboards were presented in different visual fields, localized the C1 to the striate cortex using a 2-dipole BESA approach. Di Russo, Martinez, and Hillyard (2003) used sinusoidally modulated black and white checkerboard circles in the four different hemifields (upper-right, upper-left, lower- right, and lower-left) to look at the location of the C1.
The cap of Volvopluteus asiaticus is between in diameter, more or less ovate or conical when young, then expands to convex or flat, it can have an umbo at center in mature specimens; the surface is markedly viscid in fresh basidiocarps and rugose, with powdery, minute, whitish scales. The color varies from greyish brown to brown, with a dark brown center. The gills are crowded, free from the stipe, ventricose, up to broad; white when young and turning pink with age. The stipe is long and wide, clavate with a bulbous base; the surface is white, smooth or striate.
His discovery of cells in the brain with very high sensitivity to the intensity of light, luxotonic cells, now known to be linked to the dilation of the pupils, maintenance of the body's circadian rhythm, as well as the effects of stimulating the hippocampus and the amygdala on memory. His work established the basis for our understanding of cross hemisphere memory encoding and recall. Other research he conducted includes investigation into the structure and response to stimuli in the striate cortex of macaque monkeys, and a variety of behavioral experiments using electrical stimulation of areas in the brains of cats.
The limit between these two parts of the wing is not very definite and somewhat variable. In the dark costal part lighter, yellowish brown, irregular patches are found, one large indistinct at the middle of the costa and one small rather more distinct costal spot at the beginning of the cilia. In the dorsal light part of the wing are ill-defined darker shadings and the veins are indicated darker so as to produce a striate effect. On the fold at the basal one-third is a small nearly black spot which seems to be constant.
The wingspan is about 32 mm. The forewings are pale rust-brownish, with a dorsal shade near the base, two costal shades before the middle, and another from beyond the middle to the apex, together with several obliquely transverse striate shades above the middle. All dark tawny brown, the intervening spaces partially suffused with pale tawny the light chestnut-brown ground colour showing also a considerable admixture of paler brownish ochreous. A tawny brown transverse spot, at the end of the cell, is preceded by another on the fold and a narrow marginal shade of the same colour occurs along the termen.
These receptive fields tend to be larger than those in the striate cortex and often extend across the midline to unite the two visual half fields for the first time. IT neurons are selective for shape and/or color of stimulus and are usually more responsive to complex shapes as opposed to simple ones. A small percentage of them are selective for specific parts of the face. Faces and likely other complex shapes are seemingly coded by a sequence of activity across a group of cells, and IT cells can display both short or long term memory for visual stimuli based on experience.
Scaevola parvifolia is an, erect, many-stemmed perennial growing to 60 cm tall, with hairs at 90°; stems scarcely striate. The basal leaves have no stalks, are linear to lanceolate, entire, with leaf blades 18–35 mm long by 3–6 mm wide. The leaves on the stems, however, are ovate to linear, with blades which are 1.5 to 27 mm long. The inflorescences are thyrses (compound inflorescences ending in a vegetative bud and with mixed types of branching with the main axis bearing several or many lateral cymes),which are up to 40 cm long.
The exterior may be smooth or roughened, with a wing or raphe (ridge), aril or one to two tails, rarely hairy, but may be dull or shiny and the lack of a black integument distinguishes them from related taxa such as Allioideae that were previously included in this family, and striate (parallel longitudinally ridged) in the Steptopoideae. The hilum (scar) is generally inconspicuous. The bitegmic (separate testa and tegmen) seed coat itself may be thin, suberose (like cork), or crustaceous (hard or brittle). The endosperm is abundant, cartilaginous (fleshy) or horny and contains oils and aleurone but not starch (non-farinaceous).
Visual cortex: V1; V2; V3; V4; V5 (also called MT) The visual cortex is the largest system in the human brain and is responsible for processing the visual image. It lies at the rear of the brain (highlighted in the image), above the cerebellum. The region that receives information directly from the LGN is called the primary visual cortex, (also called V1 and striate cortex). It creates a bottom-up saliency map of the visual field to guide attention or eye gaze to salient visual locations, hence selection of visual input information by attention starts at V1 along the visual pathway.
Drawing of juvenile shell of Anostoma depressum. The shell of this species is biconvex, the altitude about half the diameter, angular at the periphery, whitish, more or less brown- tinted, the base dappled with oblong spots or streaks arranged concentrically, having a dark band along the basal suture, the upper surface sparsely spotted near the periphery, and having a brown band revolving below the suture, usually with a fainter one above it. Surface is finely striate above and below, fresh specimens showing dense fine spiral lines, especially on the last whorl. The shell is composed of 4 whorls, that are nearly flat.
The Rotaliida are an order of Foraminifera, characterized by multilocular tests (shells) composed of bilamellar perforate hyaline lamellar calcite that may be optically radial or granular. In form, rotaliid tests are typically enrolled, but may be reduced to biserial or uniserial, or may be encrusting with proliferated chambers. Chambers may be simple or subdivided by secondary partitions; the surface is smooth, papillate, costate, striate, or cancellate; the aperture is simple or with an internal toothplate, entosolenian tube, or hemicylindrical structure; it may have an internal canal or stolen systems. Rotaliids are primarily oceanic benthos, although some are common in shallower estuarine waters.
Visual representation of the parvocellular and magnocellular pathways Parasol ganglion cells are the first step in the magnocellular pathway of the visual system. They project from the retina via the optic nerve to the two most ventral layers of the LGN, which is a nucleus of the thalamus, occupied by the magnocellular cells which then mainly project to the striate cortex (V1), typically to the layer 4Cα. Eventually, the information these cells collect in the retina is sent to various parts of the visual cortex, including the posterior parietal cortex and area V5 through the dorsal stream, and the inferior temporal cortex and area V4 through the ventral stream.
Silaum silaus is an erect, glabrous umbellifer with woody, stout and cylindrical tap roots, which are hot and aromatic. S. silaus has dark grey or black petioles at the top; petiole remains are found at the bottom of the stem, which is solid and striate. Its umbels are 2–6 cm in diameter, are terminal or axillary, and compound, with 4 to 15 angled rays of 1–3 cm; the peduncle is larger than the rays, and both are papillose. The flowers are mostly hermaphroditic. Silaum silaus has 2–4-pinnate leaves, which have a triangular and lanceolate outline, a long petiole and the primary divisions are long-stalked.
The ocular dominance columns cover the primary (striate) visual cortex, with the exception of monocular regions of the cortical map corresponding to peripheral vision and the blind spot. If the columns corresponding to one eye were colored, a pattern similar to that shown in the accompanying figure would be visible when looking at the surface of the cortex. However, the same region of cortex could also be colored by the direction of edge that it responds to, resulting in the orientation columns, which are laid out in a characteristic pinwheel shape. Similarly, there are columns in the cortex that have high levels of the protein cytochrome oxidase.
This information moves through an area of the brain called the lateral geniculate nucleus, located in the thalamus, and on to be processed in the primary visual cortex, area V1 (also known as the striate cortex because of its striped appearance). People with damage to V1 report no conscious vision, no visual imagery, and no visual images in their dreams. However, some of these people still experience the blindsight phenomenon, though this too is controversial, with some studies showing a limited amount of consciousness without V1 or projections relating to it. The superior colliculus and prefrontal cortex also have a major role in awareness of a visual stimulus.
The body is oval or ovate, dorsal region elevated, lateral lobes regular in shape, outline of the edges convex, not meeting; tentacles well-developed, grooved and truncated; eyes immersed immediately behind the tentacles; foot linear, adapted for clasping seaweed; the whole upper surface garnished with more or less numerous cirrigerous appendages. Tail is long, compressed and lance- pointed. Color: grass green, mottled with darker, sometimes dotted minutely with brown, or a few blue spots margined with black along the edge of the lateral lobes and on the neck. The shell is thin, pellucid, fragile, white, slightly convolute, obliquely finely striate, left side slightly inflated.
The hyperpallium (formerly called the hyperstriatum or the wulst) is the destination for lemnothalamic projections in birds. The projections as well as the granular cells at the destination of the lemnothalamic projections to the hyperpallium are similar in morphology, electrophysiology, retinotopic organization, and columnar organization to the striate cortex in mammals. These avian granular cells are thought to have evolved independently in birds, as they do not appear in reptiles. The projections originate in the dorsal lateral geniculate nucleus and target three layers in the hyperpallium: the hyperpallium intercalatum, the hyperpallium densocellularis, and the nucleus interstitialis hyperpalii apicalis, with the densest projections being to the later two layers.
Wingan Inlet is the only significant geographical feature in the area, that could be described as a lagoon that could provide shelter for a small open boat. Otherwise Bass referred to the sheltered bay and beach area in front of Wingan Inlet, that was named Fly Cove by Bass.[5] Bass' party lost an anchor in the Cove, before continuing to navigate to Wilson's Promontory where they made an attempt to cross Bass Striate to reach the Sydney Cove. Due to bad weather and a leaking boat, Bass was forced to return to the mainland and continued west where he discovered and examined Western Port.
Axo-axonic synapses are found In the visual cortex (in V1 and V2) in mammals, and have been well studied in cats, rats and primates such as monkeys. The synapse is formed on the initial segments of the axons of pyramidal cells in several layers in the visual cortex. The projecting neurons for these synapses come from various parts of the central nervous system and neocortex. Similarly, axo-axonic synapses are found in the motor cortex, in the subiculum and in the piriform cortex. In the striate cortex, as the Golgi’s method and electron microscopy revealed, as many as five axo-axonic synapses are formed onto a single pyramidal cell.
Komatsu and colleagues (Komatsu et al., 2000) recorded activity of cells of the blind spot representation in monkey striate cortex (area V1) and found some cells, in layers 4–6, that responded to large stimuli covering the blind spot (the condition under which filling-in is perceived), but not to small stimuli near the blind spot. A neuronal circuitry seems to exist that elaborates and transmits colour and brightness information through the blind region. Though intriguing, these results cannot be easily generalized to similar phenomena, such as the filling-in of illusory contours or the filling-in through artificial scotomata or adapted edges (such as in the Troxler's effect).
With such stimuli, the brightness of the central patch appears to modulate, despite the absence of luminance change. In this condition, cat retinal ganglion cells and lateral geniculate nucleus cells, having their receptive fields centred in the uniform grey patch, did not respond; on the other hand, primary visual cortex neurons were modulated by luminance changes far outside their receptive fields. Together, these results suggest that neurons in the retina and LGN are responsive to luminance modulation, but their response does not correlate with perceived brightness. On the other hand, striate neurons responded to stimulus conditions producing changes in brightness in the area corresponding to the receptive field.
Hubel and Wiesel showed that receptive fields and thus the function of cortical structures, as one proceeds out from V1 along the visual pathways, become increasingly complex and specialized. From this it was postulated that information flowed outwards in a feed forward fashion; the complex end products eventually binding to form a percept. However, via fMRI and intracranial recording technologies, it has been observed that the activation time of successive levels of the hierarchy does not correlate with a feed forward structure. That is, late activation has been observed in the striate cortex, markedly after activation of the prefrontal cortex in response to the same stimulus.
With 14 early blind subjects the study group Uhl was able to show that specific changes occurred in occipital and basal temporo-occipital brain areas only, whereby the primary visual cortex plays an important role. Subcomponents of Braille reading were correlated in different ways: a) Passive tactile stimulation, b) Active tactile pattern recognition and c) mental imagery of Braille. Although Braille reading is tactile, it does not activate the somatosensory cortex, but the primary visual cortex (striate area) or area 17. Thus the visual cortex remains a cortex for the orientation in space as well as for reading in general including reading Braille with fingers when reading with the eyes fails.
The whorls show a conspicuous shoulder, above which a slightly concave spirally striate anal fasciole extends to the appressed suture, which on the last whorl or two shows indications of a marginal thickening. The axial sculpture consists of (on the body whorl, about fifteen) protractive short riblets with subequal or slightly shorter interspaces apparently confined to the periphery: these are crossed by t\ro strong spiral threads, the posterior largest and forming oblong tumid nodules at the intersections. The anterior thread is also but less conspicuously nodulous or undulated. The rest of the surface is covered with fine spiral threads, of which there are three between the two large ones above mentioned.
The short gills are truncate to subtruncate to subattenuate to attenuate to attenuate in steps, unevenly distributed, of diverse lengths, and plentiful. The stem is 52-150 (5.2–15 cm) × 7–14 mm (0.7-1.4 cm), usually narrowing upward, infrequently narrowing downward, flaring at the top, yellow to white or very pale yellowish white and pruinose to finely powdery above the ring, white to yellow or occasionally with scattered yellowish surface fibrils and fibrillose below the ring, sometimes silky longitudinally striate. The bulb is 15 - 25 × 15 – 21 mm, more or less turnip-shaped, with light red-pinkish stains; interior of the bulb is often the place where wine-red staining first appears intensely.
The recurrent artery of Heubner, Heubner's artery or medial striate artery is named after the German paediatrician Otto Heubner and is a branch of the anterior cerebral artery, most often arising from the A1-A2 junction (44%) or the proximal A2 segment (43%), or more rarely from the A1 segment. Its vascular territory is the anteromedial section of the caudate nucleus and the anterioinferior section of the internal capsule, as well as parts of the putamen and septal nuclei. In cases of obstructed flow in the Heubner's artery, the individual may experience infarction in those subcortical areas and thus hemiparesis. More proximal portions of the artery may cause spastic paraparesis and sensory loss contralateral to the lesioned side.
The line of Gennari (also called the "band" or "stria" of Gennari) is a band of myelinated axons that run parallel to the surface of the cerebral cortex on the banks of the calcarine fissure in the occipital lobe. This formation is visible to the naked eye as a white strip running through the cortical grey matter, and is the reason the V1 in primates is also referred to as "striate cortex." The line of Gennari is due to dense axonal input from the thalamus to layer IV of visual cortex. The structure is named for its discoverer, Francesco Gennari, who first observed it in 1776 as a medical student at the University of Parma.
In a further study published in Neurocase in 2008, Baron-Cohen, Bor and Billington investigated whether Tammet's synaesthesia and Asperger syndrome explained his savant memory abilities. They concluded that his abilities might be explained by hyperactivity in one brain region (the left prefrontal cortex), which results from his Asperger syndrome and synaesthesia. On the Navon task, relative to non-autistic controls, Tammet was found to be faster at finding a target at the local level and to be less distracted by interference from the global level. In an fMRI scan, "Tammet did not activate extra-striate regions of the brain normally associated with synaesthesia, suggesting that he has an unusual and more abstract and conceptual form of synaesthesia".
Mammals include oncilla (Leopardus tigrinus), coypu (Myocastor coypus), deer, lowland paca (Cuniculus paca) and white-lipped peccary (Tayassu pecari). The mangroves are refuges for locally or regionally threatened species including bare-throated tiger heron (Tigrisoma mexicanum), American yellow warbler (Setophaga petechia), crab-eating raccoon (Procyon cancrivorus), American crocodile (Crocodylus acutus) and spectacled caiman (Caiman crocodilus). Common bivalves include Anomia fidenas, Gould's shipworm (Bankia gouldi), pleasure oyster (Crassostrea corteziensis), thin purse-oyster (Isognomon janus), striate piddock (Martesia striata) and brown falsejingle (Pododesmus foliatus). Common gastropods include mangrove periwinkle (Littoraria scabra), Littorina fasciata, Littorina varia, Littorina zebra, great pond snail (Lymnaea stagnalis), Melampus carolinus, Nassarius wilsoni, ornate nerite (Nerita scabricosta'), Thais kiosquiformis and Theodoxus luteofasciatus.
Once the receptive field of a cell had been completely mapped out, it was found that some of the simple cell receptive fields mapped out had a region which excited for a stimulus sandwiched between two inhibitory regions. These inhibitory and excitatory regions together formed a single receptive field selective for stimulus shape fitting within the excitatory region. Only a bar of light stimulus oriented at the correct angle and position within the receptive field covering only the excitatory region excluding the two inhibitory regions would express the greatest increase in the rate of impulse activity for that cell. Some layers of the striate cortex were found to contain orientation and direction selective cells.
1,66 to 2,18 mm high and 1,01 to 1,20 mm wide Shell subfusiform, with, somewhat of a quadrangular outline, thin and semitransparent, very glossy, horn-color, with a faint tinge of yellow, very slightly and remotely striate in the line of growth; periphery rounded, with a tendency to angularity; epidermis thin; whorls 4 ½ or 5, very convex and cylindrical, gradually increasing in size, the penultimate whorl as broad as the last, which occupies about two-fifths of the shell. Spire is shortish, but rather tapering, and blunt at the point. Suture is very deep. Aperture is semioval, contracted or sinuous in the middle of the outer edge; teeth six or seven, viz.
When it was first discovered by Jeffreys and Axford (1972), they suggested that the source of the C1 component was somewhere in the V1 (or the striate cortex or Brodmann's Area 17) as the polarity reversals and the reversals from side to side mirrored the retinotopic map of V1. More specifically, they suggested that the C1 is generated in Brodmann's Area 17 or the V1. In the early years the findings of some studies helped to support this hypothesis (Mangun et al., 1993; Parker, Salzen, & Lishman, 1982). Conversely, others found that the C1 might be located in areas such as Brodmann's Area 18 (Lesevre, 1982) or Brodmann's Area 19 (Maier, Dagnelie, Spekrijse, & van Dijk, 1987).
Salvadora persica is a large, well-branched evergreen shrub or small tree having soft whitish yellow wood. The bark is of old stems rugose, branches are numerous, drooping, glabrous, terete, finely striate, shining, and almost white. Leaves are somewhat fleshy, glaucous, 3.8–6.3 by 2–3.2 cm in size, elliptic lanceolate or ovate, obtuse, and often mucronate at the apex, the base is usually acute, less commonly rounded, the main nerves are in 5–6 pairs, and the petioles 1.3–2.2 cm long and glabrous. The flowers are greenish yellow in color, in axillary and terminal compound lax panicles 5–12.5 cm long, numerous in the upper axils, pedicels 1.5–3 mm long, bracts beneath the pedicels, ovate and very caduceus.
Psilocybe tampanensis fruit bodies and spore prints of cultivated specimens The cap ranges in shape from convex or conic with a slight umbo, expanding in age to become flattened or with a slight central depression; it reaches diameters of . The surface is smooth, not striate (grooved), ochraceous brown to straw brown, buff to yellowish-grey when dry, with slight bluish tones at the margin, hygrophanous, and somewhat sticky when wet. The gills are more or less adnate (broadly attached to the stem slightly above the bottom of the gill, with most of the gill fused to the stem) and brown to dark purple brown in color with lighter edges. The stem is long, thick, and equal in width throughout to slightly enlarged near the base.
Shell up to 12.0mm in length, ovate and soild, some specimens broader than others, teleconch of only 3-3 ½ convex whorls, protoconch of 1 ½ embryonic whorls, partly macroscopically axially striate; shell smooth except for very fine axial growth lines and a heavy, flattish spiral cord at base of body whorl. Aperture moderately narrow, outerlip thickened but not strongly variced, interior with 4-5 denticles decreasing in size anteriorly. Columella concave and with a moderately broad and thick callus, a strong fold at the anterior end and occasionally with another weak plication; siphonal notch deep and broad, parietal denticle swollen, anal canal distinct. Color fawn to brown, last whorl decorated with a moderately broad, interrupted brown subsutural band and a broad dark brown band on the posterior half.
The cap of A. spreta measures around 58 – 154 mm (5.8 - 15.4 cm) wide, with whitish or pallid tints of gray and/or brown at first, often darkening to gray-brown or brown-gray, often darkest in the center, often white or nearly white at the margin, having minute colorless spots and/or giving the impression of densely placed radial fibers embedded in the cap skin. In addition, the cap is broadly campanulate to plano-convex, and eventually has a large umbo in a slight depression. The cap is viscid to tacky and dull to shiny to subshiny with drying, and it has a decurved, short- striate margin. The volva is either absent or present as white to pale gray, scant, irregular patches, soft to smooth, easily removable, and membranous.
The columella is strong and thick, arcuate above, spread upon the body whorl and nearly over the umbilicus in a pad of callus, which is either white, pink or deep crimson. The callus is kidney-shaped, but slightly convex, filling the umbilicus except a narrow chink. From the outer termination of the callus an arcuate groove extends to the base of the columella, within which the surface of the shell is radiately finely striate and darker colored.Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia Radula of Ethalia guamensis Radula: The teeth, especially those of the central part are very thin and transparent, without distinct cusps; the rhachidian tooth (R) is broadly winged, bow- shaped, at its upper part it is thickened, a true cusp cannot be detected.
According to its definition (which is admitted to be in need of revision), Funga Nordica also lists Melanoleuca brachyspora, Melanoleuca brevispora, Melanoleuca robertiana and Melanoleuca stridula as synonyms of M. melaleuca. The older treatments use various characteristics to delimit the species, for instance Moser distinguishes M. melaleuca as not having a pruinose cap, with a long stem in relation to the cap diameter, having a dark brownish cap colour, with stem not coarsely striate, and having white stem flesh. Another species which has been confused with M. melaleuca is Melanoleuca polioleuca. In Species Fungorum (the part of Index Fungorum which evaluates current names), apart from the valid entry of M. melaleuca, there is an invalid one designated "Melanoleuca melaleuca sensu NCL" which is said to be equivalent to the current M. polioleuca.

Through experimentation, they found that each neuron in the cortex is responsible for a small region of the visual field and also has its own orientation specificity. From the results of these single cell readings in the striate cortex and lateral geniculate, Hubel and Wiesel postulated that simple cortical receptive fields gain complexity and an intricate spatial arrangement through the patterned convergence of multiple "on" or "off" projections from lateral geniculate cells onto single cortical cells. Hubel and Wiesel's investigation of the cat visual cortex sparked interest in the feature detection hypothesis and its relevance to other sensory systems. In fact, T.H. Bullock contended in 1961 that the vestibular system was being ignored by most of the contemporary sensory system research, and he suggested that the equivalent stimulation of vestibular organs may yield similarly intriguing results.

Nine companions set out on a journey to the Westland: Aurin Striate, an acquaintance Wren and Garth befriend on their way into the city; Triss, Captain of Home Guard; Cort and Dal, Elven Hunters; Ellenroh Elessedil, current queen of the Elves; Eowen, the queen's closest friend; Gavilan Elessedil, the queen's nephew and Wren's cousin; Wren; and Garth. Ellenroh becomes fatally ill, and before she dies, she informs Wren that she is to inherit the Loden and become the Queen of the Elves after Ellenroh, though she was orphaned at birth and raised as a Rover. Upon Ellenroh's death, Eowen reveals that the demons they are trying to avoid were created as an accident by Elves. She reveals that the elves succeeded in regaining their lost magic and to protect their nation from the Federation they created an army of replica elves, but that they became addicted to the magic and transformed into the demons.
A large number of terms are used to describe seed shapes, many of which are largely self-explanatory such as Bean-shaped (reniform) – resembling a kidney, with lobed ends on either side of the hilum, Square or Oblong – angular with all sides more or less equal or longer than wide, Triangular – three sided, broadest below middle, Elliptic or Ovate or Obovate – rounded at both ends, or egg shaped (ovate or obovate, broader at one end), being rounded but either symmetrical about the middle or broader below the middle or broader above the middle. Other less obvious terms include discoid (resembling a disc or plate, having both thickness and parallel faces and with a rounded margin), ellipsoid, globose (spherical), or subglobose (Inflated, but less than spherical), lenticular, oblong, ovoid, reniform and sectoroid. Striate seeds are striped with parallel, longitudinal lines or ridges. The commonest colours are brown and black, other colours are infrequent.
The vine is glabrous throughout. The stem is subangular, striate, and rather stout. Stipules are deeply cleft into linear or subulate, gland-tipped segments. Petioles are 1 to 2 cm long, often bearing a few stiff, gland-tipped hairs. Leaves are cordate-deltoid, 4 to 7 cm long, 3 to 6 cm wide, obscurely hastate or not lobed, acute or obtusish at apex, deeply cordate at base, repand-crenulate (often with minute glands in the sinuses of the crenations at the tips of the nerves), 5-nerved, coriaceous, often sublustrous. Peduncles are solitary, 2 to 3 cm long. Bracts are 2 to 3 cm, long pectinate or once pinnatifid (segments gland-tipped, scarcely longer than width of rachis), rarely bipinnatifid, but the rachis at least 2 mm. wide. Flowers are 5 to 8 cm wide, white. Sepals are linear or linear- lanceolate, 2.5 to 3.5 cm long, 5 to 8 mm wide at base, obtuse, corniculate just below apex, the horn being up to 7 mm long, subfoliaceous.
The cap of Amanita flavorubens is 35 – 105 mm wide, yellow to brassy yellow to lemon yellow, sometimes dark orange brown, sometimes with pigment entirely washed out by rain becoming pallid, sometimes very deep wine red in its entirety due to bruising during development (Coker 1917), subovoid to hemispheric to plano-convex to convex, depressed in the center, slightly tacky to dull to subviscid to subvelvety, with an incurved or downcurved, rimose, and nonstriate margin (may become slightly striate with age). It is adorned with conspicuous, woolly to felty, yellow warts; bald underneath the warts; the margin not lined, or only faintly lined at maturity. The volva is present as yellow to orange to bright orange- yellow flocculent to confluent warts, friable, sparsely and irregularly distributed, easily removable, pulverulent, splotchy brown around the center, yellow at the edge. The flesh is 3 – 7 mm thick over the stem, thinning evenly to the margin, white or yellowish, bright yellow just under the cap skin. The gills are free to very narrowly adnate, subcrowded to crowded, creamy ivory to cream to off-white, 3 – 8 mm broad, with a white pulverulent edge and also a small decurrent tooth.
The cap of Amanita umbrinolutea is usually free of volval remnants, 45 – 90 mm wide, at first conico-paraboloid, then somewhat campanulate to convex and finally planar, umbonate, with a strongly striate margin (margins occupying around 25 - 35% of the whole cap's radius). The cap has a distinctive pattern of color, often dark in the center, then pale, then dark over the inner edges of the lamellae and on the ridges between the marginal striations and at other times pallid in the center, but also strongly zonate; intensity of pigmentation is variable, with the center ranging from umber to grayish umber-brown to beige or pale grayish brown even within a single collection. The gills are free, crowded, off-white to sordid pale cream in mass, and up to 6 mm (0.6 cm) broad; the short gills are truncate, of varying length, scattered and unevenly distributed. The stem is 115 - 185 × 6 – 11 mm, pale cream to pale beige or isabella color or pale grayish brown, with a faint appressed zigzag girdles of fibrils, with a fleshy membranous sack-like volva at the base.
