title: Binocular neurons and binocular function in monkeys and children.
abstract: Electrophysiologic studies have shown that binocular neurons of the striate cortex of monkeys are irreversibly lost when the visual axes of the eyes are optically dissociated during the first weeks of life. The present study was a behavioral investigation of monkeys reared with optical dissociation. After brief periods of experimental strabismus, the monkeys showed poor binocular summation performance and were unable to see random dot stereograms even after two years of post-treatment normal binocular vision. These monkeys' performance on the stereopsis task was virtually identical to the stereoperformance of clinically diagnosed stereoblind children.
