我们的社交能力依赖于专门的大脑系统，这些系统允许我们执行关键操作，例如解释他人的行为。这项功能性磁共振成像（fMRI）研究调查了通过观察社会互动引起的人类大脑活动是否受到凝视的调制。在扫描过程中，参与者观察了由代理人执行的社交或个人行为，这些代理人的目光可以是可用的或被掩盖的。结果表明，观察社会互动诱发活动的内侧前额叶皮层（MPFC），一个地区的经典参与社会认知的背侧部分。重要的是，该区域内的活动受到执行所观察到的动作的代理人的注视是否可用的调节。这些研究结果的影响，背内侧前额叶皮层（dMPFC）的推理过程中所发挥的作用与社会互动的考虑。
Our social abilities depend on specialized brain systems that allow us to perform crucial operations such as interpreting the actions of others. This functional magnetic resonance imaging (fMRI) study investigated whether human brain activity evoked by the observation of social interactions is modulated by gaze. During scanning participants observed social or individual actions performed by agents whose gaze could be either available or masked. Results demonstrated that the observation of social interactions evoked activity within a dorsal sector of the medial prefrontal cortex (MPFC), an area classically involved in social cognition. Importantly, activity within this area was modulated by whether the gaze of the agents performing the observed action was or was not available. The implications of these findings for a role played by the dorsal medial prefrontal cortex (dMPFC) in terms of inferential processes concerned with social interactions are considered.
