Limbic lesions and the temporal structure of redundancy.

Abstract
Monkeys with dorsolateral frontal ablations have been found able to learn go-no-go alternation despite a grave deficit in classical alternation. Subsequently, evidence has implicated certain limbic lesions in go-no-go types of task, e. g., passive avoidance and successive discriminations. This study was undertaken to test whether these limbic lesions would affect go-no-go more than classical alternation. The results supported the hypothesis that at least 2 classes of variables, 1 frontal and 1 limbic at the neural level, interact to make possible effective performance in alternation-type tasks.
