个体在接触自我反馈图像时会感到尴尬，这取决于与标准自我的内部表征的分歧程度。我们以前的工作涉及前岛叶皮层（AI）和前扣带皮层（ACC）在处理尴尬，但是，他们的确切功能的贡献仍然不确定。在这里，我们探讨了在观看自我面部图像时被他人观察对尴尬程度的影响，以及AI和ACC中的激活和连接模式。我们使用一个互动系统对健康参与者进行了功能性磁共振成像超扫描，该系统允许一个人在真实的时间内被伴侣观察。被观察增加了观看自我面部图像时报告的尴尬程度;右侧AI中自我相关活动的相应增加表明该区域在主观体验中发挥了直接作用。被观察也增加了尾侧前扣带和前额叶区域之间的功能连接，这两个区域参与了对反思自我的处理。因此，前扣带回可能作为一个枢纽，整合用于评估知觉自我面部图像的反射自我的信息。
Individuals can experience embarrassment when exposed to self-feedback images, depending on the extent of the divergence from the internal representation of the standard self. Our previous work implicated the anterior insular cortex (AI) and the anterior cingulate cortex (ACC) in the processing of embarrassment; however, their exact functional contributions have remained uncertain. Here, we explored the effects of being observed by others while viewing self-face images on the extent of embarrassment, and the activation and connectivity patterns in the AI and ACC. We conducted functional magnetic resonance imaging hyperscanning in pairs of healthy participants using an interaction system that allowed an individual to be observed by a partner in real time. Being observed increased the extent of embarrassment reported when viewing self-face images; a corresponding increase in self-related activity in the right AI suggested that this region played a direct role in the subjective experience. Being observed also increased the functional connectivity between the caudal ACC and prefrontal regions, which are involved in processing the reflective self. The ACC might therefore serve as a hub, integrating information about the reflective self that is used in evaluating perceptual self-face images.
