在H.M.中评估了各种嗅觉能力，一位接受双侧内侧颞叶切除术的患者。他在一系列气味检测、强度辨别和适应性测试中表现正常。与此形成鲜明对比的是，H. M.无法区分或识别气味的相同不同的歧视和匹配的样本任务。虽然他可以通过视觉或触觉线索来命名常见的物体，但他不能通过气味来识别它们。这些结果表明，知觉现象的气味检测和歧视是分离的大脑损伤，在内侧颞叶的结构在气味歧视中起着至关重要的作用。
A variety of olfactory capacities were evaluated in H.M., a patient with bilateral medial temporal lobe resection. He demonstrated normal performance on a battery of tests of odour detection, discrimination of intensity, and adaptation. In striking contrast, H.M. was unable to discriminate or identify odours in same-different discriminations and in matching-to-sample tasks. Although he could name common objects using visual or tactile cues, he could not identify them by smell. These results indicate that the perceptual phenomena of odour detection and discrimination are dissociable by cerebral damage, and that structures in the medial temporal lobe play a critical role in odour discrimination.
