Topic: interbrain synchrony

Social interactions imply dynamic and synergic feedback loops in which actions, reactions, and internal states of each partner is modulated by the others. In this framework, interacting brains appear to operate as an integrated system, showing shared neural dynamics coevolving over time. In-phase brain oscillation alignment have been found in interacting people, but also in monkeys, bats, and mice. However, how emotional alterations can influence interbrain synchrony (IBS) is still unclear. Here, combining microendoscopic calcium imaging within the Anterior Cingulate Cortex (ACC or Area 24) wi

Social interaction plays a pivotal role in human cognition and well-being. Hyperscanning studies of social interaction using functional near-infrared spectroscopy (fNIRS) have associated increases in interbrain synchrony with positive outcome measures of cooperation, learning, and mutual understanding. Neurofeedback, a well-established method for modulating and training brain activity, has shown promise in improving cognitive functions. Consequently, it would be advantageous to determine the feasibility of creating a neurofeedback system for enhancing interbrain synchrony to potentially benefi
