有证据表明，右半球参与处理自我相关的刺激。先前的大脑成像研究已经发现了右侧大脑区域的网络，这些区域优先对看到自己的脸而不是熟悉的其他人做出反应。鉴于自我是一个抽象的多模态概念，我们测试了这些大脑区域是否也会区分自己的声音和朋友的声音。研究人员向参与者展示了他们自己和朋友的脸部照片，并在功能磁共振成像扫描过程中听取了他们自己和朋友的声音录音。与先前的研究一致，看到自己的脸激活了右半球的额下回（IFG）、顶叶下叶和枕叶下皮层。此外，听一个人的声音也显示出右IFG的活动增加。这些数据表明，正确的IFG与处理自我相关的刺激跨多种感官形式，它可能有助于一个抽象的自我表征。
There is evidence that the right hemisphere is involved in processing self-related stimuli. Previous brain imaging research has found a network of right-lateralized brain regions that preferentially respond to seeing ones own face rather than a familiar other. Given that the self is an abstract multimodal concept, we tested whether these brain regions would also discriminate the sound of ones own voice compared to a friends voice. Participants were shown photographs of their own face and friends face, and also listened to recordings of their own voice and a friends voice during fMRI scanning. Consistent with previous studies, seeing ones own face activated regions in the inferior frontal gyrus (IFG), inferior parietal lobe and inferior occipital cortex in the right hemisphere. In addition, listening to ones voice also showed increased activity in the right IFG. These data suggest that the right IFG is concerned with processing self-related stimuli across multiple sensory modalities and that it may contribute to an abstract self-representation.
