Fig. 6.
Mean percentage correct responses in the SDR tasks before and after DL lesions. Postoperative performance is represented in five bar graphs, each of which is the average of a block of five consecutive sessions. Monkeys received 25 sessions in the postoperative phase. As this Figure shows, there was little, if any, absence of improvement in performance throughout the 25 postoperative sessions in the DL lesion group.
