从行为上看，人类比其他物种（如猴子）更善于识别人脸。然而，这种现象的神经基础仍然未知。为了阐明这一问题，我们记录了13名健康成年人在观看人脸变形为猴脸过程中的128通道高密度事件相关电位。在所有刺激中，N170和晚期正（LP）成分（400-600 ms）被引出作为颞枕区的主要成分。人脸比例越小，N170振幅越小。也延长了腹泻时间。模糊面孔的LP成分幅值大于人和猴面孔。这些结果表明：1）N170反映了物种特异性的面孔加工，2）LP成分处理面孔刺激的复杂性差异。因此，我们得出结论，物种识别开始于170 ms左右，然后在400 ms后分析面部的详细特征。
Humans are better at recognizing human faces than those of other species (e.g, monkeys) behaviorally. However, the neural basis of such phenomenon remains unknown. To elucidate this issue, a 128-ch high-density event-related potential were recorded in 13 healthy adults during viewing morphing human face into monkey face. In all stimuli, N170 and the late positive (LP) component (400-600 ms) were elicited as the major components in the temporo-occipital regions. The more the ratio of human face reduced, the smaller the N170 amplitude became. The latencies were also prolonged. The amplitudes of LP component for ambiguous face were larger than those of human and monkey face. These findings suggest that 1) N170 reflects species-specific face processing, and 2) the LP component processes the difference in complexity of face stimuli. Therefore, we conclude that the identification of species starts at around 170 ms, then detailed feature of faces are analyzed after 400 ms.
