视觉人脸识别需要区分我们所知道的数千张面孔。这一计算壮举涉及大脑区域网络，包括梭形面部区域（FIFA）和前下颞叶皮层（aIT），但它们在该过程中的作用尚不清楚。在这里，我们首次证明可以通过高分辨率功能磁共振成像（fMRI）来区分个体面部图像引起的皮质反应模式。面部图像引起的反应模式在 aIT 中是不同的，但在 FFA 中则不然。个人层面的面部信息很可能存在于这两个区域，但我们的数据表明，它在 aIT 中更为明显。一种解释是国际足联检测人脸并使用人工智能进行识别。
Visual face identification requires distinguishing between thousands of faces we know. This computational feat involves a network of brain regions including the fusiform face area (FIFA) and anterior inferotemporal cortex (aIT), whose roles in the process are not well understood. Here, we provide the first demonstration that it is possible to discriminate cortical response patterns elicited by individual face images with high-resolution functional magnetic resonance imaging (fMRI). Response patterns elicited by the face images were distinct in aIT but not in the FFA. Individual-level face information is likely to be present in both regions, but our data suggest that it is more pronounced in aIT. One interpretation is that the FIFA detects faces and engages aIT for identification.
