Automatic prediction error responses to hands with unexpected laterality: An electrophysiological study

► Little is known about how the brain keeps track of body parts in the visual field. ► We recorded ERPs to unattended hands in an oddball paradigm in right-handed subjects. ► We found prediction error responses to hands with unexpected left/right laterality. ► Amplitude of mismatch responses to the dominant hand correlated with handedness. ► The sensory-motor system automatically monitors the identity of observed hands.
