虽然嗅周皮层在陈述性记忆中的作用已经得到了很好的证实，但还不清楚嗅周皮层是否在视觉感知中起着额外的非记忆作用。最近的一份报告表明，嗅周皮层对视觉感知可能很重要，这一证据表明，患有嗅周皮层病变的猴子在困难的（但不是简单的）视觉辨别任务中受损。我们对9名健忘症患者进行了同样的任务，其中包括3名严重受损的患者，双侧嗅周皮层完全受损（E.P.，G. P.和G. T.）。患者执行所有任务以及控制。我们认为，嗅周皮质以及前外侧颞叶皮质的功能可能不同的人和猴子之间。
While the role of the perirhinal cortex in declarative memory has been well established, it has been unclear whether the perirhinal cortex might serve an additional nonmnemonic role in visual perception. Evidence that the perirhinal cortex might be important for visual perception comes from a recent report that monkeys with perirhinal cortical lesions are impaired on difficult (but not on simple) visual discrimination tasks. We administered these same tasks to nine amnesic patients, including three severely impaired patients with complete damage to perirhinal cortex bilaterally (E.P., G.P., and G.T.). The patients performed all tasks as well as controls. We suggest that the function of perirhinal cortex as well as antero-lateral temporal cortex may differ between humans and monkeys.
