Cortical, Auditory, Event-Related Potentials in Response to Periodic and Aperiodic Stimuli with the Same Spectral Envelope

Abstract

These findings indicate that both the acoustic change complex and the mismatch negativity are sensitive indexes of the neural processing of changes in periodicity, though the acoustic change complex has an advantage in terms of amplitude. The results support the possible utility of the acoustic change complex as a clinical tool in the assessment of peripheral speech perception capacity.
