Time courses of cortical beta and gamma‐band activity during listening to metronome sounds in different tempi.

Oscillatory cortical activities in beta-band (13–20 Hz) are related to a somatomotor system, and gamma-bands (20 Hz) are involved with feature binding in perception. Previously gamma-band activity in electroencephalography was found to modulate with musical pulse with a two-beat metric accent. The present study examined beta- and gamma-band activities in auditory cortices recorded via magnetoencephalography (MEG) when subjects listened to …
