Left) Diagram of the human auditory system illustrating the presumed generators of auditory evoked potentials. Right) Representative images of the auditory brainstem response (bottom), thought to be generated from the auditory brainstem and midbrain, P50 response (middle), thought to be generated from auditory subcortical generators, demonstrating responses to initial (orange) and subsequent (purple) stimuli and cortically-based (top) auditory evoked potentials.
