Event-related brain potentials isolate the motor component in a tapping task.

Abstract excerpt

Repetitive tapping is used to investigate temporal perception, memory, and reproduction. Intertap intervals and their variability, arise from cognitive and motor processes during the task. We used a measure of readiness potential onset to determine motor component latency during the timed interval. Subjects performed a paced, two-handed tapping task at four target intervals (1.5-2.75 s). Overall latency of...
