为了进一步验证和探索同步振荡脑活动支持在二元音乐表演中的人际协调行为的假设，我们同时记录了12个吉他二重奏中的每一个的大脑脑电图（EEG），这些吉他二重奏重复演奏C.G.谢德勒基于Gabor变换，从复杂的时频信号中获得了相位锁定和脑内、脑间相位相干性的指标。分析仅限于delta（1-4 Hz）和theta（4-8 Hz）频带。我们发现，在对音乐协调要求特别高的时期，额叶和中央电极的相位锁定以及脑内和脑间相位相干连接强度得到增强。相位锁定调制的实验分配的音乐角色的领导者和追随者，证实了同步振荡的功能意义的二元音乐表演。图论分析揭示了大脑内和超脑网络的小世界特性，在音乐协调期间得到增强，社区结构包括来自两个大脑的电极（超脑模块）。我们的结论是，大脑机制索引的相位锁定，相位连贯性，结构特性的脑内和超脑网络支持人际行动协调（IAC）。
To further test and explore the hypothesis that synchronous oscillatory brain activity supports interpersonally coordinated behavior during dyadic music performance, we simultaneously recorded the electroencephalogram (EEG) from the brains of each of 12 guitar duets repeatedly playing a modified Rondo in two voices by C.G. Scheidler. Indicators of phase locking and of within-brain and between-brain phase coherence were obtained from complex time-frequency signals based on the Gabor transform. Analyses were restricted to the delta (1–4 Hz) and theta (4–8 Hz) frequency bands. We found that phase locking as well as within-brain and between-brain phase-coherence connection strengths were enhanced at frontal and central electrodes during periods that put particularly high demands on musical coordination. Phase locking was modulated in relation to the experimentally assigned musical roles of leader and follower, corroborating the functional significance of synchronous oscillations in dyadic music performance. Graph theory analyses revealed within-brain and hyperbrain networks with small-worldness properties that were enhanced during musical coordination periods, and community structures encompassing electrodes from both brains (hyperbrain modules). We conclude that brain mechanisms indexed by phase locking, phase coherence, and structural properties of within-brain and hyperbrain networks support interpersonal action coordination (IAC).
