自我神经基础的探讨常基于自我相关加工的研究,涉及皮质中线结构各个脑区甚至全脑协同作用。内侧前额叶皮质及其次成分在自我相关加工中发挥重要作用:腹内侧前额叶皮质较多支持默认模式下的自我加工、自我信息的觉察和“在线”自我加工,背内侧前额叶皮质主要参与有意识的自我参照加工、自我信息的评价和“主导的”自我加工。在自我一他人表征中,自我一他人表征的情感性、认知性和文化性因素均调节内侧前额叶皮质及次成分的活动。未来在动态的时间和人际背景中解析自我加工的神经机制是重要的研究方向。
自我神經基礎的探討常基于自我相關加工的研究,涉及皮質中線結構各箇腦區甚至全腦協同作用。內側前額葉皮質及其次成分在自我相關加工中髮揮重要作用:腹內側前額葉皮質較多支持默認模式下的自我加工、自我信息的覺察和“在線”自我加工,揹內側前額葉皮質主要參與有意識的自我參照加工、自我信息的評價和“主導的”自我加工。在自我一他人錶徵中,自我一他人錶徵的情感性、認知性和文化性因素均調節內側前額葉皮質及次成分的活動。未來在動態的時間和人際揹景中解析自我加工的神經機製是重要的研究方嚮。

To explore the neural basis of the self mainly relies on the researches of self-reference process. It refers to the cooperation of various regions of cortical midline structures (CMS), or even the whole brain. In self-reference process, medial prefrontal cortex (MPFC) and its sub regions play important role: ventral-MPFC activates stronger when self in default mode, self awareness and on-line self are activated; however, dorsal-MPFC involves more when conscious self, self evolution and agentic self are activated. In self-other representation, activities of MPFC and its sub regions are modulated by the affective, cognitive and cultural factors. It's the future directions to put self in the dynamic temporal or interpersonal background to explore its neural mechanism.
