CODING AND TRANSMISSION IN THE VISUAL SYSTEM.

Abstract

The research performed was mainly in the field of single-cell recordings from cat and monkey visual areas. The chief areas explored were (1) monkey lateral geniculate recordings using stimuli of various shapes and colors, and (2) a continuation of work on visual deprivation in immature kittens. Summaries of 3 papers which treat the extension of this work into problems of binocular deprivation, strabismus, and recovery are included. A summary is also included for studies of visual areas II and III in cats (Talbot and Marshall, 1941). The following conclusions are given: (1)Damage produced at the cortical level by monocular closure is not caused by disuse, but appears to depend on the interaction of the 2 pathways; (2) lack of synergy in the input from the 2 eyes is sufficient to cause a profound disruption in the connections that subserve binocular interaction; and (3) capacity of an animal to recover from the effects of early monocular or binocular visual deprivation is severely limited, even for recovery periods of over a year.
