The effects of selective attention on chromatic processing; pattern-onset VEP responses
… studies show that attention improves visual processing. Studies of chromatic steady-state and pattern-reversal visual evoked potentials (VEPs) support this. Typically in these studies VEP stimuli are displayed at one spatial location while distracter stimuli are displayed at a different …

Contrast adaptation reveals increased organizational complexity of chromatic processing in the visual evoked potential
… that color vision comprises multiple stages of processing. Post-receptoral channels appear to consist of both a stage of broadly-tuned opponent channels that compare cone signals, and a subsequent stage, which includes cells tuned to many different directions in color space. The chromatic visual …

An electrophysiological study of chromatic processing in the human visual system. Using visual evoked potentials and electroretinograms to study cortical and retinal contributions to human trichromatic vision.
… retinal and cortical contributions to human trichromatic colour vision. Chromatic processing at the cortex level was examined using visual evoked potentials (VEPs). These responses were elicited by chromatic spot stimuli, which were manipulated in order to selectively activate the chromatic …

Temporal Characteristics of Zebrafish Cone Types and Their Role in Separate Visual Processing
<p>Chromatic and luminance information are processed separately by the visual systems of most higher vertebrates via anatomically separate pathways. Research on primates suggests that the luminance mechanism transmits information about stimulus luminance, movement, and flicker while chromatic …

Visual performance in the mesopic range
… the effects of different stimulus parameters on chromatic sensitivity, with particular emphasis on the effect of retinal illumination, and to investigate aspects of suprathreshold visual performance under mesopic conditions. All investigations were performed using visual psychophysical …
