Abstract:

It has not been clear whether or not early information processing in the human auditory cortex is altered by voluntary movements. We report a movement-related complex event-related potential CERP consisting of relatively long-lasting amplitude and phase perturbations induced in an ongoing auditory steady-state response SSR by brief self-paced finger movements. Our results suggest that processing in the auditory cortex during the first 50-100 ms after stimulus delivery is affected before, during, and after voluntary movements, beginning with a 1-2 ms delay in the SSR wave form starting 1-2 s before the movement.
