Evolutionary theories claim that dance and music have evolved as collective rituals for social bonding and signaling. Yet, neuroscientific studies of these art forms typically involve people watching video or sound recordings alone in a laboratory. Across three live performances of a dance choreography, we simultaneously measured real-time dynamics between the brains of up to 23 audience members using mobile wet-electrode EEG. Interpersonal neural synchrony (INS) in the delta band (1-4 Hz) was highest when performers directly interacted with audience members (breaking the fourth wall) and varied systematically with the dancers' movements and artistically predicted and actual continuous engagement. In follow-up studies using video recordings of the performance, we show that audience brain synchrony and engagement are highest when dance is experienced live and together. Our study shows that the ancient social functions of the performing arts are preserved in engagement with contemporary dance.
进化理论认为，舞蹈和音乐作为社会联系与信号传递的集体仪式而演变。然而，对这些艺术形式的神经科学研究通常是让人们独自在实验室观看视频或录音。在一场舞蹈编排的三场现场表演中，我们使用移动湿电极脑电图同时测量了多达23名观众大脑之间的实时动态。当表演者直接与观众互动（打破第四面墙）时，δ波段（1-4赫兹）的人际神经同步性（INS）最高，并且随舞者的动作系统变化，在艺术上可预测且与实际的持续参与相关。在后续使用表演视频记录的研究中，我们表明，当一起现场体验舞蹈时，观众大脑的同步性和参与度最高。我们的研究表明，表演艺术古老的社会功能在与当代舞蹈的互动中得以保留。
