Case A.C.A. presented an associated impairment of visual recognition and semantic knowledge for celebrities and biological objects. This case was relevant for (a) the neuroanatomical correlations, and (b) the relationship between visual recognition and semantics within the biological domain and the conspecifics domain. A.C.A. was not affected by anterior temporal damage. Her bilateral vascular lesions were localized on the medial and inferior temporal gyrus on the right and on the intermediate fusiform gyrus on the left, without concomitant lesions of the parahippocampal gyrus or posterior fusiform. Data analysis was based on a novel methodology developed to estimate the rate of stored items in the visual structural description system (SDS) or in the face recognition unit. For each biological object, no particular correlation was found between the visual information accessed through the semantic system and that tapped by the picture reality judgement. Findings are discussed with reference to whether a putative resource commonality is likely between biological objects and conspecifics, and whether or not either category may depend on an exclusive neural substrate.
病例 A.C.A. 表现出对名人及生物客体的视觉识别和语义知识的关联性损伤。该病例与以下内容相关：（a）神经解剖学相关性；（b）生物客体和同种客体领域内的视觉识别和语义之间的关系。A.C.A. 未受颞叶前部损伤的影响。她的双侧血管病变定位于右侧的内侧和下颞叶及左侧的中间梭状回，没有伴发海马旁回或后梭状回的损伤。数据分析基于一种新的方法学，旨在估计视觉结构描述系统（SDS）或人脸识别单元中存储项目的速率。对于每个生物客体，通过语义系统获取的视觉信息与通过图片现实判断获取的视觉信息之间没有发现特定相关性。研究结果与以下内容相关：生物客体和同种客体之间是否可能存在共同的潜在资源，或者这两个类别是否可能依赖于独特的神经基质。
