Social interactions require the capacity to understand both our and other's internal states. These semi-independent skills, the ability to understand oneself and others, seem to rely on the same type of representations and recruit similar brain areas. In this study, we looked at the neural basis of self and other processing in the context of an interaction with a significant other. Fourty-two participants in a monogamous relationship completed an fMRI task in which they watched a set of video-vignettes of his/her romantic partner expressing emotional contents. Participants were asked to elaborate on his/her spouse´s experience (other condition) and on his/her own experience when watching the video-vignettes (self-condition). The results showed a significant overlap in the brain activation for both conditions (e.g. anterior insula, posterior cingulate/precuneus, inferior frontal gyrus, inferior parietal lobule). In addition, the self-condition recruited brain areas associated with interoceptive processing and affect sharing (e.g., posterior insula), whereas the other-condition engaged brain areas involved in the cognitive representation of another's internal states and self-other distinction (e.g., fusiform, supramarginal gyrus, angular gyrus and temporoparietal junction).
社会互动需要理解自己和他人内部状态的能力。这些半独立的技能，即理解自己和他人的能力，似乎依赖于相同类型的表征，并招募相似的大脑区域。在这项研究中，我们在与重要他人互动的背景下研究了自我和他人处理的神经基础。 42 名处于一夫一妻制关系中的参与者完成了一项 fMRI 任务，他们观看了一系列伴侣表达情感内容的视频短片。参与者被要求详细描述伴侣在观看视频短片时的体验（他人条件）和自己的体验（自我条件）。结果表明，两种条件的大脑激活有显著重叠（例如，前岛叶、后扣带回/楔前叶、下额叶回、下顶叶 lobule）。此外，自我条件招募了与内感受处理和情感分享相关的大脑区域（例如，后岛叶），而他人条件则涉及到对他人内部状态和自我-他人区分的认知表征的大脑区域（例如，梭状回、缘上回、角回和颞顶联合区）。
