Physiological Basis of Rhythm
Human body naturally rhythmic: heartbeat, breathing, walking.
Somatic entrainment: body's response to external rhythm, notably backbeat.
Activation of motor cortex by backbeat-heavy music.
Psychological and Neurological Evidence
2007 fMRI study:
Regular, beat-based rhythms engage motor areas (basal ganglia, SMA).
Metric rhythms recruit motor planning mechanisms, triggering instinctive movement.
