Atrophy of retinal ganglion cells after removal of striate cortex in a rhesus monkey. Perception

Abstract. The retinal ganglion cells were counted in a rhesus monkey from which the striate cortex had been removed 8 years earlier, and the results compared with those obtained previously with the eyes of normal monkeys. About 80 % of the ganglion cells within 10 degrees of the fovea were missing. Peripherally their density was unaffected. The ganglion cell layer of the entire retina resembled the peripheral retina of a normal monkey, and this result helps to explain the remarkable nature of the animal's vision.
