Abstract

This study re-examines the double dissociation of tactile deficits resulting from restricted surgical removals of Brodmann's areas 1 and 2 in the postcentral gyrus of macaque monkeys. Area 1-operated animals showed selective deficits on texture tasks, roughness and line discriminations, while area 2-operated animals showed deficits only on angle tasks, size and curve discriminations. Severe deficits were evident in spite of preoperative training, forced correction trials, and the presentation of tasks of graded difficulty.
