Rhinal Cortex Removal Produces Amnesia for Preoperatively Learned Discrimination Problems But Fails to Disrupt Postoperative Acquisition and Retention in Rhesus Monkeys

To test whether the rhinal cortex (i.e., entorhinal and perirhinal cortex) plays a time-limited role in information storage, eight rhesus monkeys were trained to criterion on two sets of 60 object discrimination problems, one set at each of two different time periods separated by 15 weeks. After the monkeys had learned both sets, two grou...更多
