识别名人与陌生人面孔的功能磁共振成像

Functional MRI of the Identification of Famous and Unfamiliar Faces

探讨名人与陌生人身份判断的脑功能。6名被试参加实验,运用功能磁共振技术采集数据,AFNI软件进行统计处理。实验结果显示,名人面孔身份识别主要激活了额颞区和梭状回等,陌生人面孔识别主要激活了脑岛和梭状回。实验表明,熟悉名人面孔与陌生人面孔识别有其不同的区域;都有梭状回的视觉加工,但是激活的程度不同。

Functional Magnetic Resonance Imaging （fMRI） was used to collect the data of six subjects who participated in identifying famous and unfamiliar faces. For data preprocessing and statistical analysis, AFNI software was used. The result indicated： The identity of famous faces identification mainly activated the frontotemporal regions and the fusiform gyrus. And the activation of the insula and fusiforrn gyrus was found in the unfamiliar face identifying task. It suggested that the identification of famous and unfamiliar faces took place in different regions; vision processing of the fusiform gyrus was in the two tasks, but the fusiform gyrus was activated in different degrees.
