虽然存在许多关于自我和他人的共同神经表征的例子，但我们不知道这种共同表征如何与大脑的其他部分相互作用。此外，高层次的基于推理的共享心理化表征与低层次的基于体现/模拟的共享表征相互作用吗？我们使用功能性神经成像（fMRI）和功能连接方法来评估这些问题在高层次的推理为基础的心理化。在自我和他人的心智化过程中，腹内侧前额叶皮层、后扣带/楔前叶和颞顶交界处（TPJ）的共享心智化表征都表现出相同的功能连接模式。连接模式分布在低层次的体现神经系统，如额叶盖/腹侧前运动皮层，前额叶，初级感觉运动皮层，和presupplementary运动区。这些结果表明，相同的神经回路正在执行涉及自我和他人的心智化过程，并且这些过程的性质可能是低水平的体现过程在更高水平的基于推理的心智化中的整合。
Although many examples exist for shared neural representations of self and other, it is unknown how such shared representations interact with the rest of the brain. Furthermore, do high-level inference-based shared mentalizing representations interact with lower level embodied/simulation-based shared representations? We used functional neuroimaging (fMRI) and a functional connectivity approach to assess these questions during high-level inference-based mentalizing. Shared mentalizing representations in ventromedial prefrontal cortex, posterior cingulate/precuneus, and temporo-parietal junction (TPJ) all exhibited identical functional connectivity patterns during mentalizing of both self and other. Connectivity patterns were distributed across low-level embodied neural systems such as the frontal operculum/ventral premotor cortex, the anterior insula, the primary sensorimotor cortex, and the presupplementary motor area. These results demonstrate that identical neural circuits are implementing processes involved in mentalizing of both self and other and that the nature of such processes may be the integration of low-level embodied processes within higher level inference-based mentalizing.
