为了评估梭状回在识别和处理人类面部情绪表达中的作用，收集了MEG数据，同时6名健康受试者判断与中性面孔和等亮度混乱面孔相比，面部照片是否显示情绪（快乐或厌恶）。对于所有6名受试者，磁源定位到右侧梭状回是明显的150毫秒后，介绍了面部刺激，但不是以下非面部刺激。MEG源强度为这一组成部分是最大的快乐，中间的厌恶，和最低的中性面部表情，这表明梭状回的活动是敏感的面部特定的刺激和情感内容的脸。这些发现被认为是在一个专门的神经面依赖信息系统的背景下。
To evaluate the role of the fusiform gyrus in identifying and processing facial emotional expression in humans, MEG data were collected while six healthy subjects judged whether photographs of faces displayed emotion (happiness or disgust) compared to neutral faces and equiluminant scrambled faces. For all six subjects, a magnetic source localizing to right fusiform gyrus was evident ∼150 ms following presentation of face stimuli, but not following non-face stimuli. MEG source strength for this component was greatest for happy, intermediate for disgust, and lowest for neutral facial expressions, suggesting that activity in fusiform gyrus is sensitive to both face-specific stimuli and to the affective content of the face. These findings are considered in the context of a specialized neural face-dependent information system.
