Visual cortical lesions in the cat: A study of depth and pattern discrimination.

Abstract

Compared 10 adult cats with lesions of the lateral and suprasylvian gyri with normal Ss on series of tasks including a pattern discrimination, a visual cliff, visual placing, and a series of discrimination problems based on visual cliff cues. All lesions spared at least a small remnant of striate cortex and all Ss visually placed. Lesioned Ss were impaired in performance on some pattern problems but were able to discriminate patterns contrasting substantially in total contour length. The amount of contrast discriminated was related to the severity of the lesion. (17 ref.) (PsycINFO Database Record (c) 2006 APA, all rights reserved)
