尸检和计算机断层扫描数据的关键分析表明，面孔失认症（面部识别障碍）与双侧中央视觉系统病变有关。这些病变位于内侧枕颞区，功能对称。出现面孔失认症的主要因素是需要唤起给定视觉刺激的特定背景。刺激的模糊性（群体中不同成员在视觉上相似的频率）是辅助因素。但是，面孔失认症并不局限于人脸。这种现象与任何视觉上模糊的刺激有关，其识别依赖于上下文记忆的唤起。
Critical analysis of postmortem and CT [computed tomography] scan data indicates that prosopagnosia [facial recognition impairment] is associated with bilateral lesions of the central visual system. Those lesions are located in the mesial occipitotemporal region and are functionally symmetric. The prime factor in the appearance of prosopagnosia is the requirement to evoke the specific context of a given visual stimulus. The ambiguity of the stimulus (the frequency with which different members of a group are visually similar) is an adjuvant factor. But prosopagnosia is not specific to human faces. The phenomenon appears in relation to any visually ambiguous stimulus whose recognition depends on contextual memory evocation.
