Metacognitive awareness—the ability to know that one is having a particular experience—is thought to guide optimal behavior, but its neural bases continue to be the subject of vigorous debate. Prior work has identified correlations between perceptual metacognitive ability and the structure and function of lateral prefrontal cortex (LPFC); however, evidence for a causal role of this region in promoting metacognition is controversial. Moreover, whether LPFC function promotes metacognitive awareness of perceptual and emotional features of complex, yet ubiquitous face stimuli is unknown. Here, using model-based analyses following a causal intervention to LPFC in humans, we demonstrate that LPFC function promotes metacognitive awareness of the orientation of faces—although not of their emotional expressions. Collectively, these data support the causal involvement of the prefrontal cortex in metacognitive awareness, and indicate that the role of LPFC in metacognition encompasses perceptual experiences of naturalistic social stimuli.

侧面前额叶皮层的功能在因果关系上支持人脸的感知元认知。

元认知意识(一种知道某人正在经历某种特殊经历的能力)被认为可以指导最佳行为,但是其神经基础仍然是激烈辩论的主题。先前的工作已经确定了感知的元认知能力与外侧前额叶皮层(LPFC)的结构和功能之间的相关性。然而,有关该区域在促进元认知中起因果作用的证据尚有争议。而且,LPFC功能是否能促进对复杂而无处不在的面部刺激的感知和情感特征的元认知意识。在这里,在对人进行LPFC进行因果干预后,使用基于模型的分析,我们证明了LPFC功能可以促进对面部朝向的元认知意识,尽管不能促进面部表情的表达。总的来说,
