Color Representation Is Retinotopically Biased but Locally Intermingled in Mouse V1

Dichromatic vision is common in many mammals. However, color processing in the primary visual cortex (V1) of dichromatic mammals is relatively unknown compared to the trichromatic primates. In this study, we investigated the functional organization of color processing in mouse V1. The mouse retina has a graded expression pattern of two opsins along its dorsoventral axis. However, it is not clea...

Color contrast in macaque V1.

We explored the neural basis for spatial color contrast (red looks redder surrounded by green) and temporal color contrast (red looks redder if preceded by green) in primary visual cortex (V1) of the alert macaque. Using pairs of stimuli, we found a subset of neurons that gave stronger responses to sequences of red and green spots and stronger responses to adjacent red and green spots. These ce...

An Eecient Representation in V1

The primary visual cortex (V1) is the rst cortical area to receive visual input from the eyes. For over thirty years it has been known that the neurons in this part of the brain are sensitive to bars of light of various orientations and sizes 1]. What has been far less clear is why. In this issue, Olshausen and Field 2] describe some interesting simulations that shed light on this question. The...

Saccadic suppression of retinotopically localized blood oxygen level-dependent responses in human primary visual area V1.

Saccadic eye movements are responsible for bringing relevant parts of the visual field onto the fovea for detailed analysis. Because the retina is physiologically unable to deliver sharp images at very high transsaccadic speeds, the visual system minimizes the repercussion of the blurry images we would otherwise perceive during transsaccadic vision by reducing general visual sensitivity and inc...

Representation of Color Surfaces in V1: Edge Enhancement and Unfilled Holes.

UNLABELLED The neuronal mechanism underlying the representation of color surfaces in primary visual cortex (V1) is not well understood. We tested on color surfaces the previously proposed hypothesis that visual perception of uniform surfaces is mediated by an isomorphic, filled-in representation in V1. We used voltage-sensitive-dye imaging in fixating macaque monkeys to measure V1 population re...
