面对面模仿是一种独特的社交互动，其中基于合作伙伴的反馈执行共享动作。合作伙伴的模仿是对被模仿者行为的反馈，导致了共享行为。在面对面模仿过程中，作为主体间性的核心，行为的共享表征的神经机制并不为人所知。在这里，基于预测编码帐户，我们假设，对特定的前向内部模型是共享的动作表示，这是由镜像神经元系统的某些部分的个体间同步表示。超扫描功能磁共振成像进行了面对面的互动在16对参与者谁完成了即时模仿任务的面部表情。成对的参与者被交替分配给模仿者或被模仿者，被模仿者被提示表达快乐，悲伤或非情绪化的面孔。虽然模仿和被模仿引起的神经激活是不同的，几乎没有重叠，在线模仿互动增强了右顶下小叶的脑间同步，与面部运动运动学轮廓的相似性。这一发现表明，通过模仿性的相互作用，右下顶叶在共享作为一个对特定的前向内部模型的行动表示的关键作用。
Face-to-face imitation is a unique social interaction wherein a shared action is executed based on the feedback of the partner. Imitation by the partner is the feedback to the imitatee's action, resulting in sharing actions. The neural mechanisms of the shared representation of action during face-to-face imitation, the core of inter-subjectivity, are not well-known. Here, based on the predictive coding account, we hypothesized that the pair-specific forward internal model is the shared representation of action which is represented by the inter-individual synchronization of some portion of the mirror neuron system. Hyperscanning functional magnetic resonance imaging was conducted during face-to-face interaction in 16 pairs of participants who completed an immediate imitation task of facial expressions. Paired participants were alternately assigned to either an imitator or an imitatee who was prompted to express a happy, sad, or non-emotional face. While neural activation elicited by imitating and being imitated were distinct with little overlap, on-line imitative interaction enhanced inter-brain synchronization in the right inferior parietal lobule that correlated with the similarity in facial movement kinematic profile. This finding indicates a critical role of the right inferior parietal lobule in sharing representation of action as a pair-specific forward internal model through imitative interaction.
