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.

American Journal of EEG Technology, 1986
ABSTRACT.Our knowledge of the visual cortex has increased tremendously over the past ten years based on studies in subhuman primates. Over a dozen separate cortical visual areas have now been described in monkeys (Van Essen and Maunsell 1983). This paper will review our current understanding of the anatomy and physiology of the visual cortex in monkeys

Dynamic architecture of the visual cortex
Brain Research, 1970Several aspects of the organization of the visual cortex in the mouse have been examined in Golgi preparations. Special attention has been devoted to the afferent systems innervating the basal dendrites of pyramidal cells of layers III and V. A computer analysis using matrix algebra of the projected dendritic field of the basal and apical-collateral ...

Dopamine in the visual cortex of the cat
Experientia, 1986The endogenous content of noradrenaline (NA) and dopamine (DA) was determined by radioenzymatic assays in three different areas of the occipital (visual) cortex, in normal cats as well as in DA-deafferented animals. The use of HPLC methodology enabled us to detect and measure in addition two metabolites of DA: 3, 4-dihydroxyphenylacetic acid (DOPAC ...

Interareal synchronization in the visual cortex
Behavioural Brain Research, 1996The primary visual cortex (V1) is part of a highly interconnected network of cortical areas, hierarchically organized but operating concurrently across hierarchical levels. The high degree of reciprocal interconnection among visual cortical areas provides a framework for their interaction during the performance of visual scene analysis.

In order to understand the organization of visual spatial organization within the occipital cortex, it is necessary to review basic functional aspects of the retina and its projection to the lateral geniculate. Retinal photoreceptors actually hyperpolarize when light hits the 11-cis retinal molecule and induces molecular motion within the photoreceptor

The spatiotopic 'visual' cortex of the blind
SPIE Proceedings, 2012Visual cortex activity in the blind has been shown in sensory tasks. Can it be activated in memory tasks? If so, are inherent features of its organization meaningfully employed? Our recent results in short-term blindfolded subjects imply that human primary visual cortex (V1) may operate as a modality-independent 'sketchpad' for working memory ...
