To examine the role of primary visual cortex in visuospatial integration, we studied the
spatial arrangement of contextual interactions in the response properties of neurons in …

An orientational difference of only 0.3–0.5 deg can be discriminated between two gratings or
two lines, although psychophysical channels and cortical cells both have comparatively …

Prolonged exposure to a stimulus, called'adaptation', reduces cortical responsiveness.
Adaptation has been studied extensively in primary visual cortex (V1), where responsivity is …

The traditional picture of the early stages of sensory processing in the adult mammalian
cortex suggests that the functional properties of cortical cells and the functional architecture …

Abstract" Cognition through Color" reviews the current status of investigations of color
cognition from the standpoint of modern neuropsychology. It provides clear evidence, based …

Biological structures can be seen as collections of special devices coordinated by a matrix of
organization. Devices are dif? cult to evolve and are meticulously conserved through the …

Color perception depends profoundly on adaptation processes that adjust sensitivity in
response to the prevailing pattern of stimulation. We examined how color sensitivity and …

Cells in adult primary visual cortex are capable of integrating information over much larger
portions of the visual field than was originally thought. Moreover, their receptive field …

We propose that visual adaptation in orientation, spatial frequency, and motion can be
understood from the perspective of optimal information transmission. The essence of the …

When an image is presented to one eye and a very different image is presented to the
corresponding location of the other eye, they compete for conscious representation, such …
