社会神经科学中的一个重要问题是自我和亲密的他人在神经表征上的异同。大多数研究认为内侧前额叶皮质(MPFC)区域是参与这一过程的主要区域。然而，一些研究报告了相互矛盾的数据，这使得对这一主题的进一步调查变得非常重要。在这项功能磁共振成像(FMRI)研究中，我们研究了中国受试者被动听到自己的名字(SN)、母亲的名字(MN)和未知的名字(UN)时，扣带回前部(ACC)的脑活动。结果表明，与UN识别相比，SN知觉在一个广泛分布的双侧网络中具有较强的激活作用，该网络包括皮质中线结构(MPFC和ACC)、额下回和颞中回。与MN相比，SN激活了双侧颞上回；与SN识别相比，MN识别引起了更强的中枢和后脑区的激活。SN和MN引起重叠区域的激活，即ACC、MPFC和额叶上回。这些结果表明，中国人在加工SN和MN时使用了某些共同的脑区。本研究结果为中国人自我和亲近他人的神经基础提供了证据。
An important question in social neuroscience is the similarities and differences in the neural representations between the self and close others. Most studies examining this topic have identified the medial prefrontal cortex (MPFC) region as the primary area involved in this process. However, several studies have reported conflicting data, making further investigation of this topic very important. In this functional magnetic resonance imaging (fMRI) study, we investigated the brain activity in the anterior cingulate cortex (ACC) when Chinese participants passively listened to their self-name (SN), their mother’s name (MN), and unknown names (UN). The results showed that compared with UN recognition, SN perception was associated with a robust activation in a widely distributed bilateral network, including the cortical midline structure (the MPFC and ACC), the inferior frontal gyrus, and the middle temporal gyrus. The SN invoked the bilateral superior temporal gyrus in contrast to the MN; the MN recognition provoked a stronger activation in the central and posterior brain regions in contrast to the SN recognition. The SN and MN caused an activation of overlapping areas, namely, the ACC, MPFC, and superior frontal gyrus. These results suggest that Chinese individuals utilize certain common brain region in processing both the SN and the MN. The present findings provide evidence for the neural basis of the self and close others for Chinese individuals.
