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.

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.

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.

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.

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 ...

Organization of spatial frequency in cat striate cortex
Neuroscience, 2017Primary visual cortex, the first cortical stage of visual information processing, is represented by diverse functional maps that demonstrate the selectivity for specific visual features such as spatial frequency (SF). Although the local organization of SF maps in cat area 17 (A17) has been largely investigated, the global arrangement remains elusive ...

Neural processing in cat striate cortex
IEEE Transactions on Systems, Man, and Cybernetics, 1983The neural circuitry in the striate cortex of the cat is examined. The question is approached through an inspection of the morphological design and the functional performance of neural elements. Procedures in neurohistology are explored to reveal the fine structure of striate neurons, while recordings from microelectrodes provide the material for ...

NADPH diaphorase histochemistry in the macaque striate cortex
Journal of Comparative Neurology, 1986AbstractThe distribution of the enzyme dihydronicotinamide adenine dinucleotide phosphate (NADPH) diaphorase was examined in the striate cortex of the rhesus monkey. The pattern of activity in the neuropil matched that of cytochrome oxidase in adjacent sections and the enzymes were similarly modulated by monocular deprivation.
