Definition

The transformation of color signals and chromatic properties of receptive fields within the visual cortex of primates.

Processing of Chromatic Signals in the Early Visual Pathways

The processing of chromatic signals in the retina and lateral geniculate nucleus (LGN) has been the focus of numerous studies and is well understood. Less is known about the fate of color signals in the cortex. This entry first reviews central aspects of color processing in the primary visual cortex (V1) and discusses how it differs from subcortical processes. It then discusses the processing of color signals in extrastriate visual areas.

Color in the Striate Cortex (V1)

Chromatic Properties of Individual Neurons

In the primate primary visual cortex, it had been estimated that about 50 % of the cell population is selective for color [1]. Estimates of the proportion of color-selective cells, however, are complicated by the use of different criteria for the...
