A short analysis of the input-output organization of the primary visual cortical areas in the cat and monkey is followed by a description of the salient microelectrophysiological properties of retino-geniculo-cortical system neurons. It is concluded that a strict hierarchical model of cortical processing of visual information is no longer tenable.

Current Opinion in Neurobiology, 1993
The concept of visual association cortex derives from early myelogenetic studies, assorted cases of so-called visual agnosia and much philosophical speculation. A review of the evidence suggests that it is perhaps time to review our concept of the visual association cortex.

Human visual cortex comprises 4-6. billion neurons that are organized into more than a dozen distinct functional areas. These areas include the gray matter in the occipital lobe and extend into the temporal and parietal lobes. The locations of these areas in the intact human cortex can be identified by measuring visual field maps.

Neurons in mouse visual cortex have diverse receptive field properties and they respond selectively to specific features of visual stimuli. Owing to the lateral position of the eyes, only about a third of the visual cortex receives input from both eyes, but many cells in this region are binocular.

Microcircuits in visual cortex
Current Opinion in Neurobiology, 2002The microcircuitry of the neocortex is bewildering in its anatomical detail, but seen through the filters of physiology, some simple circuits have been suggested. Intensive investigations of the cortical representation of orientation, however, show how difficult it is to achieve any consensus on what the circuits are, how they develop, and how they ...

Visual Attention in the Prefrontal Cortex
Annual Review of Vision Science, 2022Voluntary attention selects behaviorally relevant signals for further processing while filtering out distracter signals. Neural correlates of voluntary visual attention have been reported across multiple areas of the primate visual processing streams, with the earliest and strongest effects isolated in the prefrontal cortex.

Primary visual cortex and visual awareness
Nature Reviews Neuroscience, 2003The primary visual cortex (V1) is probably the best characterized area of primate cortex, but whether this region contributes directly to conscious visual experience is controversial. Early neurophysiological and neuroimaging studies found that visual awareness was best correlated with neural activity in extrastriate visual areas, but recent studies ...

Visual cortex efference to nonprimary cortex in the cat
Brain Research, 1971Abstract Evoked potentials and corresponding extracellular single cell activity were recorded in anterior middle suprasylvian gyrus upon stimulation of ipsilateral visual cortex with single pulses in chloralosed cats. Both a short and a long latency efference from visual cortex (VC) to anterior middle suprasylvian gyrus (AMSS) were observed.

The Cerebral Cortex: Visual Cortex
Archives of Ophthalmology, 1986Brain structure involved in visual processing is examined in this new volume of The Cerebral Cortex . Ophthalmologists, particularly neuroophthalmologists, and visual scientists concerned with visual processing will benefit from this source book of detailed mammalian visual anatomy.
