为了研究面部识别的神经元基础，分析了猕猴在执行面部识别任务期间颞上沟（STS）和颞前下回（ITG）中面部神经元的活动。面部空间由面部识别任务期间面部神经元的活动组成，基于多维尺度（MDS）方法；前STS神经元组成的面部空间代表面部视图，而前ITG神经元组成的面部空间代表面部身份。还分析了动物的行为反应时间与面部相关神经元反应的潜伏期之间的时间相关性。前ITG中一些面部神经元的反应潜伏期与行为反应时间显着相关，而前STS中这种相关性不显着。未发现前ITG中面部相关神经元反应潜伏期与行为反应时间的相关性归因于反应潜伏期与神经元反应幅度之间的相关性。目前的结果表明，前部 ITG 与面部身份的判断密切相关，前部 STS 与传入感知信息的分析密切相关。猴子的面部识别可能涉及两个区域之间的相互作用。
To investigate the neuronal basis underlying face identification, the activity of face neurons in the anterior superior temporal sulcus (STS) and the anterior inferior temporal gyrus (ITG) of macaque monkeys was analyzed during their performance of a face-identification task. The face space was composed by the activities of face neurons during the face-identification task, based on a multidimensional scaling (MDS) method; the face space composed by the anterior STS neurons represented facial views, whereas that composed by the anterior ITG neurons represented facial identity. The temporal correlation between the behavioral reaction time of the animal and the latency of face-related neuronal responses was also analyzed. The response latency of some of the face neurons in the anterior ITG exhibited a significant correlation with the behavioral reaction time, whereas this correlation was not significant in the anterior STS. The correlation of the latency of face-related neuronal responses in the anterior ITG with the behavioral reaction time was not found to be attributed to the correlation between the response latency and the magnitude of the neuronal responses. The present results suggest that the anterior ITG is closely related to judgments of facial identity, and that the anterior STS is closely related to analyses of incoming perceptual information; face identification in monkeys might involve interactions between the two areas.
