The toolbox and codes of main data Social groups in various social species are organized with hierarchical structures that shape group dynamics and the nature of within-group interactions. In-group social bonding, exem- plified by grooming behaviors among animals and collective rituals and team-building activi- ties in human societies, is recognized as a practical adaptive strategy to foster group harmony and stabilize hierarchical structures in both human and nonhuman animal groups. However, the neurocognitive mechanisms underlying the effects of social bonding on hierar- chical group interactions remain largely unexplored. Here, we conducted simultaneous neural recordings on human participants engaged in in-group communications within small hierarchical groups (n = 528, organized into 176 three-person groups) to investigate how social bonding influences hierarchical interactions and neural synchronizations. We differentiated inter-personal social interactions between individuals of different (inter-status) or same (intra-status) social status and observed distinct effects of social bonding on inter-status and intra-status interac- tions. Specifically, social bonding selectively increased inter-status information exchange and prefro
