Effects of Voluntary Movements on Early Auditory Brain Responses,

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.
