Visual discrimination in the absence of visual cortex
Behavioural Brain Research, 1987Normal rats and rats with devascularization lesions ranging from subtotal removals of striate cortex (Area 17) to complete removal of neocortex were trained in a horizontal/vertical stripe discrimination for a liquid reinforcer. Subgroups of animals were identified on the basis of size and location of lesion (with particular reference to striate 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.

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 ...

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.

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.

Selective attention gates visual processing in the extrastriate cortex.
Science, 1985Single cells were recorded in the visual cortex of monkeys trained to attend to stimuli at one location in the visual field and ignore stimuli at another. When both locations were within the receptive field of a cell in prestriate area V4 or the inferior

Mnemonic coding of visual space in the monkey's dorsolateral prefrontal cortex.
Journal of Neurophysiology, 19891. An oculomotor delayed-response task was used to examine the spatial memory functions of neurons in primate prefrontal cortex. Monkeys were trained to fixate a central spot during a brief presentation (0.5 s) of a peripheral cue and throughout a ...

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.

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.
