Synchronizing with auditory and visual rhythms: An fMRI assessment of modality differences and modality appropriateness

► fMRI study of finger tapping with visual flashes, moving bar, auditory beeps, siren. ► Visuo-motor synchrony improved with moving bar; audio-motor degraded with siren. ► Putamen activation reflected stability of sensorimotor synchrony, not modality. ► No modality difference in tapping or timing circuit with modality-appropriate stimuli.
