Directed motor-auditory EEG connectivity is modulated by music tempo (2017)
Journal Article

Beat perception is fundamental to how we experience music, and yet the mechanism behind this spontaneous building of the internal beat representation is largely unknown. Existing findings support links between the tempo (speed) of the beat and enhanc... Read More about Directed motor-auditory EEG connectivity is modulated by music tempo.
