面部感知对于灵长类动物来说是一项至关重要的技能。在人类和猕猴中，功能性磁共振成像（fMRI）揭示了一个皮质区域系统，与物体图像相比，当受试者观看面部图像时，该系统显示出血流量增加。然而，尚未研究这些功能磁共振成像识别区域内单个神经元的刺激选择性。我们使用功能磁共振成像来识别和定位两只猕猴中最大的面部选择区域，以进行单单元记录。该区域几乎所有（97％）的视觉反应神经元都具有强烈的面部选择性，表明存在专门的皮质区域来支持猕猴的面部处理。
Face perception is a skill crucial to primates. In both humans and macaque monkeys, functional magnetic resonance imaging (fMRI) reveals a system of cortical regions that show increased blood flow when the subject views images of faces, compared with images of objects. However, the stimulus selectivity of single neurons within these fMRI-identified regions has not been studied. We used fMRI to identify and target the largest face-selective region in two macaques for single-unit recording. Almost all (97%) of the visually responsive neurons in this region were strongly face selective, indicating that a dedicated cortical area exists to support face processing in the macaque.
