Abstract

Temporal contiguity between an action and its auditory feedback is crucial to perceive self-generated sound. However, neural mechanism for motor-auditory temporal integration has remained largely unknown. Here, we employed four experiments to uncover specific event-related potentials (ERPs) elicited by delayed auditory feedback of self-generated action with an oddball experimental paradigm. Our results clearly demonstrate that different neural mechanisms are employed for the processing of temporally-deviant and pitch-deviant auditory feedbacks and that the time window for subjective motor-auditory integration is likely about 200 ms, manifested in these auditory ERP components.
