大脑通过感官和运动过程实现的动作与世界互动。这些互动的很大一部分是由两个或两个以上的人同步的目标导向的行动。超扫描技术，同时从两个人的功能磁共振成像评估已经开发出来。然而，EEG记录，允许在更高水平的时间分辨率的同步神经元活动的评估还没有同时在多个人进行评估，并在时间-频率域进行分析。在这项研究中，我们同时记录了8对吉他手一起演奏一首短旋律的大脑脑电图，以探讨在人际协调行动过程中同步皮层活动的程度和功能意义。通过将同步算法应用于脑内和脑间分析，我们发现大脑内部和大脑之间的相位同步在（i）准备节拍器克里思设置和（ii）协调播放开始期间显着增加。从脑内动力学中提取的相位对齐与吉他手之间的行为演奏开始相关。我们的研究结果表明，人际协调的行动之前，并伴随着脑间振荡耦合。据推测，这些耦合反映了个体感知和行为的时间属性的相似性。脑间振荡耦合是否在启动和维持人际行动协调中起因果作用，需要进一步的研究来澄清。
Brains interact with the world through actions that are implemented by sensory and motor processes. A substantial part of these interactions consists in synchronized goal-directed actions involving two or more individuals. Hyperscanning techniques for assessing fMRI simultaneously from two individuals have been developed. However, EEG recordings that permit the assessment of synchronized neuronal activities at much higher levels of temporal resolution have not yet been simultaneously assessed in multiple individuals and analyzed in the time-frequency domain. In this study, we simultaneously recorded EEG from the brains of each of eight pairs of guitarists playing a short melody together to explore the extent and the functional significance of synchronized cortical activity in the course of interpersonally coordinated actions. By applying synchronization algorithms to intra- and interbrain analyses, we found that phase synchronization both within and between brains increased significantly during the periods of (i) preparatory metronome tempo setting and (ii) coordinated play onset. Phase alignment extracted from within-brain dynamics was related to behavioral play onset asynchrony between guitarists. Our findings show that interpersonally coordinated actions are preceded and accompanied by between-brain oscillatory couplings. Presumably, these couplings reflect similarities in the temporal properties of the individuals' percepts and actions. Whether between-brain oscillatory couplings play a causal role in initiating and maintaining interpersonal action coordination needs to be clarified by further research.
