An examination of the relationship between the physical stimulus and the neuroelectric events involved in visual perception and discrimination. The data indicate that certain elemental relations of psychophysics reflect properties of retinal behavior. Electrical correlates of flicker fusion, intensity encoding, and spatial and temporal contrast are seen in the spike trains of ganglion cells. The concept that some psychophysical relations are mediated primarily in the retina, along with the neuroelectrical and neuroanatomical indications that centrifugal control at this level is small, suggests that the retina would be a promising point of entry for understanding some of the neural mechanisms subserving vision.
