与面部处理相关的大脑区域对特定功能的选择性程度仍然存在争议。此外，关于面部反应大脑区域对人脸的选择性程度，我们知之甚少。为了研究面部处理的区域选择性，我们使用功能性磁共振成像来检查整个大脑对人脸，狗脸和房屋的反应。14名健康的右撇子志愿者参与了一项被动观看、封闭的实验。结果表明，外侧梭状回（Brodmann的第37区）最大限度地响应狗和人的面孔时，与其他网站相比，其次是中/下枕回（BA 18/19）。房屋与狗和人脸激活的部位包括内侧梭状回（BA 19/37）、后扣带回（BA 30）和上级枕回（BA 19）。唯一的网站，显示显着差异的激活狗和人的脸是舌/内侧梭状回。在这个网站上，房子引起了最强的激活，其次是狗的脸，而对人脸的反应是可以忽略不计的，并没有不同的固定。海马旁回/杏仁核是唯一的网站，显示显着激活人类的面孔，但没有狗的面孔或房屋。(C)2004 Elsevier B.

The extent to which the brain regions associated with face processing are selective for that specific function remains controversial. In addition, little is known regarding the extent to which face-responsive brain regions are selective for human faces. To study regional selectivity of face processing, we used functional magnetic resonance imaging to examine whole brain activation in response to human faces, dog faces, and houses. Fourteen healthy right-handed volunteers participated in a passive viewing, blocked experiment. Results indicate that the lateral fusiform gyrus (Brodmann's area 37) responds maximally to both dog and human faces when compared with other sites, followed by the middle/inferior occipital gyrus (BA 18/19). Sites that were activated by houses versus dog and human faces included the medial fusiform gyrus (BA 19/37), the posterior cingulate (BA 30), and the superior occipital gyrus (BA 19). The only site that displayed significant differences in activation between dog and human faces was the lingual/medial fusiform gyrus. In this site, houses elicited the strongest activation, followed by dog faces, while the response to human faces was negligible and did not differ from fixation. The parahippocampal gyrus/amygdala was the sole site that displayed significant activation to human faces, but not to dog faces or houses. (C) 2004 Elsevier B.V. All rights reserved.
