The Visual Cortex

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

Functional Organization of the Visual Cortex

1983
Publisher Summary Although the cortex is in many ways a uniform structure, different regions of cortex are devoted to very different purposes, ranging from sensory perception to motor control to higher intellectual functions. Within the sensory cortex, one finds a further spatial segregation of the modalities. The focus of this chapter is the primary

Computations in the early visual cortex

Journal of Physiology-Paris, 2003
This paper reviews some of the recent neurophysiological studies that explore the variety of visual computations in the early visual cortex in relation to geometric inference, i.e. the inference of contours, surfaces and shapes. It attempts to draw connections between ideas from computational vision and findings from awake primate electrophysiology. In

Plasticity of cat visual cortex

Experimental Neurology, 1980
Abstract Monocular eyelid closure in kittens mimics certain visual deficits in humans that result in amblyopia ex anopsia. I have now studied the effects of monocular eyelid closure in cat upon the slow-wave response recorded from visul cortex. The pattern of changes in the response closely paralleled the changes in visual function of the amblyopic ...

The Visual Cortex

2016
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

Is there Lateral Inhibition in the Visual Cortex?

Nature New Biology, 1971
AN acute angle appears to be less acute than it really is1,2. The effect has an obvious similarity to the tilt after-effect, the only difference in procedure being that the lines forming the acute angle are presented simultaneously in one case and successively in the other.

Interareal synchronization in the visual cortex

Behavioural Brain Research, 1996
The 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.

Visual cortex in the albino rabbit

Experimental Brain Research, 1987
Cortical projection of the visual field on the albino rabbit's cortex has been investigated and compared with that in the pigmented rabbit. A lower magnification of the projection of the temporal visual streak (nasal visual field) in the albino rabbit is attributed to the absence of an area centralis-like organization of the retinal ganglion cells in ...
