Dr. Laurel Trainor's graduate student, Hector Orozco Perez, will lead a discussion on the article by Sänger et al., 2012 entitled "Intra- and interbrain synchronization and network properties when playing guitar in duets". Abstract listed below.   

For those of you who are new:

The McMaster Institute for Music and the Mind hosts a monthly Seminar/Journal Club. The purpose of the club is for MIMM members and other interested people from different areas to meet to discuss recent papers of broad interest in the field of music cognition. Everyone is welcome! Our current journal club members include psychologists, musicians, mathematicians, engineers, music teachers, graduate and undergraduate students, and interested community members.

Sänger, J., Müller, V., & Lindenberger, U. (2012). Intra-and interbrain synchronization and network properties when playing guitar in duets. Frontiers in Human Neuroscience6, 312.


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).
