Stereoscopic Vision in the Cat


STEREOPSIS is the perception of relative depth by means of the disparate retinal stimulation which occurs when horizontally separated eyes are fixed on a common point. The stimulus conditions which produce stereopsis in humans have been studied thoroughly, but only recently has it been possible to study the neural mechanisms1–4. We have been able to demonstrate stereoscopic vision in the cat, a result which complements neurophysiological data demonstrating the presence of cells in cat visual cortex with receptive field geometry which is specialized for the detection of retinal disparity1,2.
