A quarter of a century ago, the first systematic behavioral experiments were performed to
clarify the nature of color constancy—the effect whereby the perceived color of a surface …

▪ Abstract The visual image formed on the retina represents an amalgam of visual scene
properties, including the reflectances of surfaces, their relative positions, and the type of …

We investigated the responses of single neurons in primary visual cortex (area V1) of awake
monkeys to chromatic stimuli. Chromatic tuning properties, determined for homogeneous …

When the illumination on a scene changes, so do the visual signals elicited by that scene. In
spite of these changes, the objects within a scene tend to remain constant in their apparent …

Applying a synthesis procedure that promotes alloy formation, highly-dispersed alumina-
supported Pt–Pd catalysts spanning the Pt-rich half of the composition range were prepared …

Seminal work in the early nineties revealed that the visual receptive field of neurons in cat
primary visual cortex can change in location and size when artificial scotomas are applied …

It is often stated that color is selectively processed in cortical area V4, in both macaques and
humans. However most recent data suggests that color is instead processed in region (s) …

Color constancy—by which objects tend to appear the same color under changes in
illumination—is most likely achieved by several mechanisms, operating at different levels in …

The brightness and color of a surface depends on its contrast with nearby surfaces. For
example, a gray surface can appear very light when surrounded by a black surface or dark …

The contribution that different brain areas make to primate color vision, especially in the
macaque, is debated. Here we used functional magnetic resonance imaging in the alert …
