Four rhesus monkeys (Macaca mulatta) were trained preoperatively in a test of object-in-place scene memory. They were presented daily with lists of unique computer-generated scenes each containing a spatial array of multiple individual objects. Within each scene, objects to be discriminated appeared in the foreground, each occupying a unique location, and monkeys were required to correctly discriminate the rewarded object to receive a food reward. Once this preoperative criterion was attained, the monkeys received bilateral entorhinal cortex ablation performed as either one or two surgical operations with a period of testing following each. Postoperatively, they were significantly impaired in learning new object-in-place scene problems. These results show that the entorhinal cortex, like anatomically related structures including the perirhinal cortex and the fornix, contributes to object-in-place scene learning.
