摘　　要：自我觉知是个体对自己有所认识或意识的内部主观状态,自我认知加工的任务都激发了自我觉知,因此,其复杂性导致脑机制研究存在很多的争议。对自我觉知神经机制的研究多从认知神经精神医学和涉及自我觉知任务的脑成像的角度进行,很多研究发现自我觉知更多地激活了右脑,针对具体的任务而激活不同脑区;但复杂的、高水平的自我觉知任务往往涉及内部言语加工,需要左脑的加入。现在越来越多的研究认为皮质中线结构对自我觉知具有重要作用。今后有关自我觉知神经机制的研究可望从自我觉知的性质、所涉及的具体任务水平及社会文化背景的差异等方面有所进展。Self-awareness refers to the inner subjective state of individual when he is aware of himself. Almost all tasks involved self may arouse self-awareness. Due to its complexity, there remain many disputes about the neural mechanism of self-awareness. The researches of neural mechanism proceed from cognitive neuropsychiatry and neural imaging. Many researches find that self-awareness activates the right hemisphere. Furthermore, some high-level tasks involve with inner speech activate the left hemisphere. Nowadays, more researchers consider the cortical middle structure plays important role in self-awareness. Specific tasks relate to self-awareness and social background should be paid more attention in the future study.
