Abstract

Human color vision is subserved by the interaction of three classes of cones. Recent anatomical and physiological studies raised questions about the ways in which these receptors interact to form the receptive fields of retinal ganglion cells. We are studying the organization of these receptive fields in the retinae of anesthetized and paralyzed macaque monkeys at various retinal eccentricities, employing novel stimulation techniques that allow us to determine the amount and nature of contributions from the various cone classes to the center and surround of each receptive field. The results of these experiments will be discussed in the context of recent psychophysical measurements of human color vision.
