Viewing the faces of familiar people selectively activates a distributed network of brain regions implicated in both the perceptual and non-perceptual processing of conspecifics. In this fMRI study, we investigate the influence of depth of famous-face processing on this network, comparing a passive incidental face-processing to a task that required the extraction of identity and biographic information. We observed that the precuneus, ventromedial prefrontal cortex (vmPFC), anterior temporal face patch (ATFP) and the amygdala exhibit a selective response even during incidental face processing. At the same time<s>,</s> face selectivity was enhanced in the lateral anterior temporal lobe (ATL) and the posterior superior temporal sulcus (pSTS) when identity and information extraction was required. Additionally, goal-directed identity and information extraction was associated with a recruitment of inferior frontal gyrus (IFG), while this region was deactivated during passive viewing. Collectively, these results show that components of the extended system reflect both the passive and active retrieval of person-related knowledge, and that the active access to such knowledge may potentially be mediate control circuits in the IFG.

fMRI 对知觉和非知觉皮层区域自动和有目的的熟悉面孔处理的反应。

查看熟悉的人的面孔有选择地激活大脑区域的分布式网络，该网络涉及同种人的知觉和非知觉处理。在这项 fMRI 研究中，我们调查了著名面孔处理深度对该网络的影响，将被动的附带面孔处理与需要提取身份和传记信息的任务进行比较。我们观察到楔前叶、腹内侧前额叶皮层 (vmPFC)、前颞面部斑块 (ATFP) 和杏仁核即使在附带的面部处理过程中也表现出选择性反应。同时，当需要身份和信息提取时，<s>,</s> 外侧前颞叶 (ATL) 和后颞上沟 (pSTS) 的面部选择性增强。此外，目标导向身份和信息提取与额下回 (IFG) 的募集相关，而该区域在被动观看期间被停用。总的来说，这些结果表明扩展系统的组件反映了与人相关的知识的被动和主动检索，并且对此类知识的主动访问可能是 IFG 中的中介控制电路。
