High-resolution receptive field measurements in primate retinal ganglion cells, and their implications for color vision

Abstract

Identifying the connectivity of the myriad neurons within a circuit is key to understanding its function. We developed a novel technique to map the functional connectivity between thousands of cone photoreceptors and hundreds of ganglion cells in the primate retina. These measurements reveal the nature of cone sampling by midget ganglion cells, providing insight to the origins of red-green color opponency.
