Internalized Timing of Isochronous Sounds Is Represented in Neuromagnetic Beta Oscillations

Using magnetoencephalography (MEG), this study demonstrates that the brain's beta-band (approximately 20 Hz) neural oscillations encode an internalized sense of musical beat timing. Beta oscillations increase in amplitude during the anticipated beat intervals even when sounds are omitted, revealing that the brain actively predicts rhythmic timing through neural oscillation dynamics — a key finding supporting the neural resonance account of rhythm perception.
