Delineation of the striate cortex, and the striate-peristriate projections in the guinea pig

Experimental Brain Research, 1991
The size and position of the guinea pig area 17 were determined by transneuronal labeling after intraocular injections of 3H-proline or WGA-HRP. Area 17 occupies a large region of the occipital cortex located between two shallow fissures, the fissura sagittalis lateralis and the lateral groove.

Coverage and the design of striate cortex

Biological Cybernetics, 1991
Hubel and Wiesel (1977) suggested that ocular dominance and orientation columns in the macaque monkey striate cortex might be bands of uniform width that intersected orthogonally. They pointed out that if this were the case, there would be an equal allocation of cells of different orientation preference to each eye and to each point in visual space ...

Cytoplasmic laminar bodies in the striate cortex

Journal of Ultrastructure Research, 1969
A laminated cytoplasmic inclusion consisting of curved parallel arrays of thick-walled microtubules separated by a layer of granular dense material has been identified in neurons within the visual cortex of a monkey. This body appears to be a continuation of the granular endoplasmic reticulum and previously has been noted in neurons related to other ...

Nongeniculate afferents to striate cortex in macaques

Journal of Comparative Neurology, 1983
AbstractHorseradish peroxidase (HRP) was injected in relatively massive amounts to cover most, or portions, of opercular striate cortex in four macaques. Absence of transcallosal or circumventricular labelling, plus discrete and consistent retrograde labelling in other areas in the four cases, assured the validity and specificity of the observations ...

Set Size Effects in the Macaque Striate Cortex

Journal of Cognitive Neuroscience, 2003
Abstract Attentive processing is often described as a competition for resources among stimuli by mutual suppression. This is supported by findings that activity in extrastriate cortex is suppressed when several stimuli are presented simultaneously, compared to a single stimulus.

silent periodic cells in the cat striate cortex

Vision Research, 1982
A class of neurons called silent periodic cells, having properties intermediate between those in the simple and complex families, has been discriminated in the cat striate cortex. Silent periodic cells have relatively small receptive fields, a low spontaneous activity (i.e.

The geometry of the topographic map in striate cortex

Vision Research, 1989
Johnston (1986) proposed that the global geometry of the striate cortical map in primates can be understood with reference to a conic surface in visual space oriented with its base in the plane of the eye and axis along the line of sight. Here, cortical magnification data from the macaque, squirrel and cebus monkeys and distance data from topographic ...

Neurophysiology of the Striate Cortex

1994
Recent findings on the structural and functional properties of the striate cortex of cats and primates are briefly reviewed. In particular these findings show that: i) different stimulus attributes are processed at least partially in parallel, ii) the responses of single neurones to a given visual stimulus are context-dependent, iii) some degree of ...

The Design of Striate Cortex

1991
Our lack of knowledge about the functions of most regions of the brain makes it difficult to discuss how different parts of it may have evolved, and why particular brain regions are differently organised in different species. It is relatively easy to understand why the shape of a bird’s beak varies from one species to the next, since the function of ...

Volumetric asymmetry in the human striate cortex

Experimental Neurology, 1985
A sample of 31 serially sectioned human brains, in age from 33 weeks of gestation through 94 years, was examined for volumetric asymmetries in the striate cortex. The right striate cortex was found to be larger than the left in 24 of 31 cases.
