This study examined the neural substrates of facial familiarity and person-knowledge. Based on current neural models of face perception, it was hypothesized that distinct extended networks of brain regions differentiate the perception of (a) novel faces, (b) novel faces associated with person-knowledge, (c) perceptually familiar faces and (d) familiar faces for which person-knowledge was learned. To test this hypothesis, we conducted an event-related functional magnetic resonance imaging experiment during which participants viewed faces experimentally manipulated to represent these different levels of familiarity. Results confirmed that distinct networks of brain regions, particularly the medial prefrontal cortex, underlie the perception of faces for which person-knowledge is available.
本研究考察了面部熟悉度和人物知识的神经基础。基于当前的面孔知觉神经模型，我们假设不同的扩展脑区网络可以区分（a）新面孔、（b）与人物知识相关的新面孔、（c）知觉熟悉的面孔和（d）熟悉面孔及其相关的人物知识。为了验证这一假设，我们进行了一项事件相关的功能性磁共振成像实验，参与者在实验中观察了不同熟悉度的面孔。结果证实，大脑中特别是内侧前额叶的不同区域网络，是人物知识可用于面孔知觉的基础。
