Chromatic sensitivity and spatial organization of cat visual cortical cells: cone-rod interaction

Abstract

1. Colour sensitivity and spatial organization were determined for the dominant-eye receptive fields of thirty-eight simple or complex cells in cat primary visual vortex. Receptive fields were all from the cortical area associated with central vision. Each cell was investigated with threshold or suprathreshold monochromatic stimuli, under scotopic, low and high mesopic adaptation.
