✅   Neural oscillatory dynamics in joint action: distinct contributions of entrainment and beta modulation to self/other integration

science

Temporal coordination plays a pivotal role in human activities, enabling effective communication and collaboration. Yet, the neural mechanisms supporting this ability remain poorly understood. Recent research suggests that synchronized beta modulation across individual brains, as measured via EEG hyperscanning, may reflect a shared sensorimotor framework underpinning interpersonal synchronization. Building on the idea that self/other integration is a key mechanism in this process, behavioral studies have shown that adopting a partner's first person visual perspective (1P) enhances interpersonal coordination, as opposed to the natural second person perspective (2P). Here, we used the body swap illusion in immersive virtual reality to directly manipulate embodied perspective and investigate its neural consequences.
