功能性神经影像学已经揭示了几个大脑区域对其他人的视觉外观，特别是面部有选择性。最近的证据表明，外侧颞区对人体的视觉外观（纹外体区或EBA）做出反应。我们测试了这个区域是否区分了自我中心和以他人为中心的观点。EBA活动显着增加allocentric相对于自我中心的观点在右半球，但不受身份。全脑分析揭示了几个受观点或身份影响的区域。EBA活动的调制观点是温和的相对调制刺激类。我们认为EBA在社会愿景中扮演着相对早期的角色。
Functional neuroimaging has revealed several brain regions that are selective for the visual appearance of others, in particular the face. More recent evidence points to a lateral temporal region that responds to the visual appearance of the human body (extrastriate body area or EBA). We tested whether this region distinguishes between egocentric and allocentric views of the self and other people. EBA activity increased significantly for allocentric relative to egocentric views in the right hemisphere, but was not influenced by identity. Whole-brain analyses revealed several regions that were influenced by viewpoint or identity. Modulation of EBA activity by viewpoint was modest relative to modulation by stimulus class. We propose that the EBA plays a relatively early role in social vision.
