难以识别和区分一个人的情绪是述情障碍的主要特征。本研究采用20项多伦多述情障碍量表，探讨梭状回对面部情绪的自动激活及其在述情障碍中的作用。中间。3特斯拉功能磁共振成像扫描，照片的脸轴承悲伤，快乐，和中性表情掩盖了中性的面孔，22名健康的成年人谁也回答了多伦多述情障碍量表。选择梭状回作为感兴趣区域，提取该区域的体素值，总结为平均值，并在不同条件（悲伤、快乐和中性面孔）之间进行测试。面具悲伤的面部情绪与更大的双边激活梭状回比面具中立的面孔。分量表，困难识别的感觉，呈负相关，梭状回的神经反应掩盖悲伤的面孔。相关结果提示，梭状回对负性情绪刺激的自动低反应性可能反映了人们在日常生活中对情绪的识别问题。
Difficulties in identifying and differentiating one's emotions are a central characteristic of alexithymia. In the present study, automatic activation Of the fusiform gyrus to facial emotion was investigated as it function Of alexithymia as assessed by the 20-item Toronto Alexithymia Scale. During. 3 Tesla fMRI scanning, pictures of faces bearing sad, happy, and neutral expressions masked by neutral faces were presented to 22 healthy adults who also responded to the Toronto Alexithymia Scale. The fusiform) gyrus was selected as the region of interest, and voxel Values Of this region were extracted, summarized as means, and tested among the different conditions (sad, happy, and neutral faces). Masked sad facial emotions were associated with greater bilateral activation of the fusiform gyrus than masked neutral faces. The subscale, Difficulty Identifying Feelings, was negatively correlated with the neural response of the fusiform gyrus to masked sad faces. The correlation results Suggest that automatic hyporesponsiveness Of the fusiform gyrus to negative emotion stimuli may reflect problems in recognizing one's emotions in everyday life.
