Effects of caudate lesions on signaled and nonsignaled sidman avoidance in the rat

Rats with caudate lesions were clearly deficient on a nonsignaled Sidman avoidance schedule when compared with both normal subjects and subjects with cortical control lesions. Caudate subjects responded at lower rates, avoided a lower percentage of shocks, and failed to develop a temporal discrimination. In contrast with its effects upon normals and controls, the addition of a 5-sec warning cue failed to improve the performance of the caudate subjects.
