Rhythmic stimuli are powerful because their regularity enables us to predict when important events will happen and, as a result, to attend to those points in time in order to process these important events optimally. Rhythms are ubiquitous in biological systems, from motor movements to locomote to communication signals such as speech and music. In the human case, I will present neuroscientific evidence that the auditory system uses the motor system to accomplish rhythmic timing, and that auditory-motor interactions for timing are present very early in development. Further, I will present studies showing that brain oscillations in the beta frequency (~20 Hz), measured with EEG, entrain to external auditory rhythms, and that fluctuations in beta power are a neural signature of the prediction of upcoming sounds. I will also discuss the social implications of regular predictive movements, showing that even in infants, moving in synchrony with another person leads to increased prosocial behaviour targeted at that person. Finally, I will describe our unique LIVELab research-concert hall facility (LIVELab.mcmaster.ca) and the research we are doing there. Analysis of the data we collect requires complex signal processing and machine learning approaches and I look forward to your thoughts and input.
