Visual response latencies in striate cortex of the macaque monkey.

Journal of Neurophysiology, 1992
1. Many lines of evidence suggest that signals relayed by the magnocellular and parvocellular subdivisions of the primate lateral geniculate nucleus (LGN) maintain their segregation in cortical processing.

Spatiotemporal organization of simple-cell receptive fields in the cat's striate cortex. II. Linearity of temporal and spatial summation.

Journal of Neurophysiology, 1993
1. We have tested the hypothesis that simple cells in the cat's visual cortex perform a linear spatiotemporal filtering of the visual image. To conduct this study we note that a visual neuron behaves linearly if the responses to small, brief flashes of ...

Organization of spatial frequency in cat striate cortex

Neuroscience, 2017
Primary 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 ...

Bursts and recurrences of bursts in the spike trains of spontaneously active striate cortex neurons.

Journal of Neurophysiology, 1985
Simultaneous recordings were made from small collections (2-7) of spontaneously active single units in the striate cortex of unanesthetized cats, by means of chronically implanted electrodes.

Quantitative studies of single-cell properties in monkey striate cortex. I. Spatiotemporal organization of receptive fields.

Journal of Neurophysiology, 1976
1. The properties of single cells in striate cortex of the rhesus monkey, representing the visual field 2 degrees -5 degrees from the fovea, were examined quantitatively with stationary and moving stimuli. Three distinct classes of cells were identified:

Deoxyglucose analysis of retinotopic organization in primate striate cortex.

Science, 1982
We have anatomically analyzed retinotopic organization using the 14C-labeled 2-deoxy-D-glucose method. The method has several advantages over conventional electrophysiological mapping techniques.

The ipsilateral field representation in the striate cortex of the opossum

Experimental Brain Research, 1988
Reference axes for the visuotopic study of the opossum's striate cortex were estimated from corresponding binocular response fields using multi-unit recording. These central binocular axes (CBA) were derived from experimental data based on the concept that corresponding receptive fields for each eye should be mostly in register under natural conditions.

Neural processing in cat striate cortex

IEEE Transactions on Systems, Man, and Cybernetics, 1983
The 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, 1986
AbstractThe 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.
