Distinct neuronal entrainment to beat and meter: Revealed by simultaneous EEG-fMRI

In this study, we used a paradigm to induce neuronal entrainment to beat and meter and obtained images of the neuronal populations with an electroencephalogram functional magnetic resonance imaging (EEG-fMRI) fusion method. We observed that some neuronal populations, including the bilateral putamen, bilateral caudate, left thalamus, and supplementary motor area (SMA), entrain to both beat and meter. We also observed that the bilateral putamen entrains more to meter and the SMA entrains more to beat. Our results suggest that the bilateral putamen plays an important role in meter perception.
