Social interactions occur in group settings and are mediated by communication signals that are exchanged between individuals, often using vocalizations. The neural representation of group social communication remains largely unexplored. We conducted simultaneous wireless electrophysiological recordings from the frontal cortices of groups of Egyptian fruit bats engaged in both spontaneous and task-induced vocal interactions. We found that the activity of single neurons distinguished between vocalizations produced by self and by others, as well as among specific individuals. Coordinated neural activity among group members exhibited stable bidirectional interbrain correlation patterns specific to spontaneous communicative interactions. Tracking social and spatial arrangements within a group revealed a relationship between social preferences and intra- and interbrain activity patterns. Combined, these findings reveal a dedicated neural repertoire for group social communication within and across the brains of freely communicating groups of bats.
社会互动发生在群体环境中，并由个体之间交换的通信信号介导，这些信号通常使用声音进行传递。群体社交通信的神经表示形式在很大程度上仍未被探索。我们同时对参与自发和任务诱导发声互动的埃及果蝠群体的额皮质进行了无线电生理记录。我们发现，单个神经元的活动可以区分自发声和他发声，以及特定个体之间的声音。群体成员之间协调的神经活动表现出与自发交际互动特异性相关的稳定的双向脑间相关模式。跟踪群体内的社会和空间排列揭示了社会偏好与脑内和脑间活动模式之间的关系。综上所述，这些发现揭示了蝙蝠自由交流群体的大脑内和大脑间的群体社交通信的专用神经储备库。
