Neurophysiology of the Striate Cortex
1994Recent 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 ...

An interpretation of image processing in striate cortex
Proceedings of IEEE International Conference on Systems, Man and Cybernetics, 2002It has been proposed that the simple cells of visual cortex perform either a localized Fourier transform of the image or a wavelet transform. We argue that a short term Fourier transform is unlikely since the required cells with multi-lobed receptive fields are rare or non-existent.

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, 1985A 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.

Much of what is known about the role of human striate cortex in vision comes from the study of dysfunction in patients with specific lesions of visual pathways, from the retina to the occipital lobe and the adjoining temporal and parietal regions. That evidence depends on neuro-ophthalmological, neuropsychological, and psychophysical techniques.

1. Most studies of cortical neurons have focused on the spatial structure of receptive fields. For a more complete functional description of these neurons, it is necessary to consider receptive-field structure in the joint domain of space and time.

Development of synapses in macaque monkey striate cortex
Visual Neuroscience, 1992AbstractA quantitative electron-microscopic (EM) analysis of the development of synaptic density (number of synapses/100 μm neuropil) has been done in primary visual cortex (striate, area 17) of the Old World monkey Macaca nemesthna. A comparative EM morphological study of developing synaptic contacts also was done in the same tissue.

Visualization Of Neuronal Activity In Monkey Striate Cortex
Annual Review of Physiology, 1989The greatest recent success at describing the functional anatomy of one neocortical area was achieved by Hubel & Wiesel (11) whose work on primary visual (striate) cortex has provided tantalizing information about the topographical organization of two response properties, ocular dominance and orientation selectivity.

Callosal projections of the striate cortex in the neonatal rabbit
Experimental Brain Research, 1981Callosal fiber projections of the striate cortex were studied in newborn rabbits using the methods of 1) retrograde transport of horseradish peroxidase (HRP) and 2) orthograde transport of tritiated leucine. Data collected from 6-8 day old animals revealed not only the existence of adult-like commissural fibers in the lateral striate cortex bordering ...

Anatomical Demonstration of Columns in the Monkey Striate Cortex
Nature, 1969Anatomical investigation of the monkey striate cortex supports the physiological concept that the cortex is subdivided vertically into columnar aggregates of cells. Here the shape and size of two independent and overlapping column systems are described.
