The medial temporal lobe (MTL) has been considered traditionally to subserve declarative memory processes only. Recent studies in nonhuman primates suggest, however, that the MTL may also be critical to higher order perceptual processes, with the hippocampus and perirhinal cortex being involved in scene and object perception, respectively. The current article reviews the human neuropsychological literature to determine whether there is any evidence to suggest that these same views may apply to the human MTL. Although the majority of existing studies report intact perception following MTL damage in human amnesics, there have been recent studies that suggest that when scene and object perception are assessed systematically, significant impairments in perception become apparent. These findings have important implications for current mnemonic theories of human MTL function and our understanding of human amnesia as a result of MTL lesions.
传统上认为内侧颞叶（MTL）仅参与陈述性记忆过程。然而，最近对非人类灵长类动物的研究表明，MTL对高阶感知过程可能也至关重要，其中海马体和嗅周皮质分别参与场景和物体感知。本文回顾了人类神经心理学文献，以确定是否有证据表明这些相同观点也适用于人类MTL。尽管大多数现有研究报告称，人类失忆症患者MTL受损后感知功能完好，但最近有研究表明，当系统评估场景和物体感知时，感知功能会出现明显损伤。这些发现对当前关于人类MTL功能的记忆理论以及我们对MTL损伤导致的人类失忆症的理解具有重要意义。
