寻找自我:基于认知神经的观点

Find the Self:Based on the Perspective of Cognitive Neuroscience

默认网络相关研究表明,生物进化的社会适应性建构了自我的认知神经基础,与James的自我结构相对应:主我位于后部扣带回,精神自我位于内侧前额叶,身体自我位于顶下小叶和脑岛;并且与内侧前额叶、顶下小叶和后部扣带回之间的信息传递相关。个体在基线水平的大脑活动表明,自我是通过后部扣带回接收并调节全脑(包括表征客我的脑区)信息流,随时准备将外界满足需要有利于个体生存的资源纳入其中的神经系统。对于探讨"认识自我"这个古老的哲学问题与现代认知神经科学之间的关系有重要意义。

The researches on the default network show that social adaptiveness of biological evolution constructs the neural basis of the self,corresponding to the James＇ s division of the self：the＂I＂was associated with the posterior cingulate gyrus,the spiritual self was associated with medial prefrontal cortex,physical self was associated with the inferior parietal lobule and the insula. Moreover,the medial prefrontal cortex and the inferior parietal lobe send information to the posterior cingulate gyrus. The baseline of the brain activity demonstrates that the self can be seen as a system,which receives and modulates information flows in the whole brain（ including the area representing ＂Me＂） through the posterior cingulate gyrus,and is ready to incorporate survival resources that met individual needs into itself. It is important for exploring the relationship between the ancient philosophical problem of self and modern cognitive neuroscience.
