MEG Data

The human brain exhibits coordinated information processing among brain regions, resembling units in social organisations. Understanding how these brain regions operate and collaborate is a scientific question with great importance and challenge. This study draws an analogy between brain regions and social organisations and explores whether the brain operates in a decentralized or centralized mode by employing a social interaction perception task. We utilized magnetoencephalography technology to analyze the dynamic processes involved in perceiving the social interactions of others. Our findings reveal that the brain strikes a balance between centralized and decentralized modes. When confronted with information of low ambiguity, the brain leaned towards decentralized decision-making, showcasing a decentralized mode. In high-ambiguity conditions, the superior temporal sulcus takes on a dominant role, indicating a more centralized control mechanism. Our findings indicate adaptive decision-making processes in the human brain, tactically shifting between centralized and decentralized strategies to enhance information processing efficiency.

人类大脑的多个脑区之间存在协同信息处理机制，该过程恰似社会组织中的各个职能单元。探究这些脑区的运作与协作模式，是一项兼具重要学术价值与挑战性的科学问题。本研究将脑区与社会组织进行类比，通过社交互动感知任务，探究大脑的运作究竟属于去中心化还是中心化机制。我们采用脑磁图（magnetoencephalography）技术，分析了个体感知他人社交互动时的动态神经过程。研究结果显示，大脑在中心化与去中心化模式之间维持着动态平衡。当面对低歧义性信息时，大脑更倾向于采用去中心化决策，展现出去中心化的运作模式。在高歧义性情境下，颞上沟（superior temporal sulcus）会占据主导地位，表明此时大脑采用了更为中心化的调控机制。本研究结果表明，人类大脑具备适应性决策机制，会通过在中心化与去中心化策略间灵活切换，以提升信息处理效率。
