支持社会认知的神经网络的控制对于社会互动至关重要。特别是，模仿的控制与互动质量直接相关，与以社交困难为特征的障碍相关的障碍。先前的研究表明，下额叶皮层（IFC）和颞顶交界区（TPJ）参与控制模仿，但这些地区的功能作用仍然不清楚。在这里，经颅直流电刺激（tDCS）被用来提高皮质兴奋性IFC和TPJ完成三项任务之前：（一）自然的社会互动，在此期间，增加模仿是已知的，以提高融洽，（二）选择反应时间任务，其中模仿需要被抑制成功的性能和（iii）非模仿控制任务。相对于假刺激，刺激IFC改善了情境依赖控制的模仿-参与者模仿更多的社会互动和模仿抑制任务期间。相比之下，刺激TPJ减少了在抑制任务中的模仿，而不影响社会交往中的模仿。刺激部位均不影响非模仿控制任务。这些数据支持一个模型，其中IFC调制模仿直接根据任务的要求，而TPJ控制任务适当的转移注意力向代表性的自我或其他，间接影响模仿。
The control of neurological networks supporting social cognition is crucially important for social interaction. In particular, the control of imitation is directly linked to interaction quality, with impairments associated with disorders characterized by social difficulties. Previous work suggests inferior frontal cortex (IFC) and the temporoparietal junction (TPJ) are involved in controlling imitation, but the functional roles of these areas remain unclear. Here, transcranial direct current stimulation (tDCS) was used to enhance cortical excitability at IFC and the TPJ prior to the completion of three tasks: (i) a naturalistic social interaction during which increased imitation is known to improve rapport, (ii) a choice reaction time task in which imitation needs to be inhibited for successful performance and (iii) a non-imitative control task. Relative to sham stimulation, stimulating IFC improved the context-dependent control of imitation—participants imitated more during the social interaction and less during the imitation inhibition task. In contrast, stimulating the TPJ reduced imitation in the inhibition task without affecting imitation during social interaction. Neither stimulation site affected the non-imitative control task. These data support a model in which IFC modulates imitation directly according to task demands, whereas TPJ controls task-appropriate shifts in attention toward representation of the self or the other, indirectly impacting upon imitation.
