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 1Damage 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.
