Performance on delayd matching-to-place and delayd matching-to-color was assessed in Japanese monkeys with separate ablations of the posterior parahippocampal and perirhinal cortex, as well as in unoperated controls. Lesions of posterior parahippocampal cortex yielded severe impairments in delayd matching-to-place task, but showed no impairment in delayd matching-to-color. On the other hand, lesions of perirhinal cortex produced severe impairments in both tasks of delayd matching-to-place and delayd matching-to-color. Thus, the present results suggest that the posterior parahippocampal and perirhinal cortex possessed different functional significance from each other in visual recognition memory. However, it will be necessary to perform further investigation, since the lesions of posterior parahippocampal and perirhinal cortex enchroached, respectively, on the hippocampus and the entorhinal cortex.

在单独消融后海马旁和嗅周皮质的日本猴以及未手术对照组中评估了延迟匹配位置和延迟匹配颜色的性能。海马后旁皮质损伤对位置延迟匹配任务有严重损害，但对颜色延迟匹配任务无损害。另一方面，嗅周皮层的损伤产生严重的障碍，在这两个任务的延迟匹配到位置和延迟匹配到颜色。因此，本研究结果表明，后海马旁皮质和嗅周皮质在视觉识别记忆中具有不同的功能意义。然而，这将是必要的，进行进一步的调查，因为后海马旁和嗅周皮质的病变，分别在海马和内嗅皮质。
