自我和他人的协调与心理理论的神经机制

Neural Mechanism at the Self─Others Coordination in Theory of Mind

有关心理理论神经机制的研究远未达到共识。从自我与他人协调的角度看，可认 它是一个由多脑区有机组织而成的系统。自我中心化偏差是人类认知的一种默认选译，要正确理解他人的心理状态，需要抑制自我中心偏差。因此，心理理论的加工至少包括以下几个不同的过程；通过仿真自我理解他人，相应的加工脑区为镜像神经元系统；从他人与客体形成二元关系中表征心理状态的内容，相应脑区是颞顶联合区；对仿真自我进行抑制，相应脑区为背外侧额叶；以及整合协调以上几个过程，其脑区可能是内侧前叶。

The neural mechanism in Theory of Mind has not yet led to a consensus. However， if we examine it from the self─others coordination， we could regard it as a systematical functions on multiple brain areas. As egocentrism bias is a default mode of the human cognition， inhibition would be necessary for appropriate attribution to the others’ mental state. Hence， at least the following four processes are needed：（a）simulation would be made by the mirror neuron system when the mental state between the self and the others is consistent；（b）representation generated about the mental state which based on the others─objects dyadic relationship is responded to the temporoparietal junction：（c）the inhibition to simulation would be functioned by the dorsolateral frontal lobe；（d）and the coordination of all above processes would be purposed by the medial prefrontal cortex.
