Auditory deprivation time and implantation age are important factors affecting the auditory and speech rehabilitation outcomes of cochlear implantation(CI)in patients with congenital deafness possibly associated with the functional level of the auditory cortex at different developmental stages.In terms of predicting preoperative efficacy,evaluating postoperative efficacy of CI,and conducting research on neurological,psychiatric,and psychological related diseases,the functional evaluation of the auditory cortex is essential.Methods for evaluating auditory cortex function encompass neuroelectrophysiology,morphology,functional imaging,and molecular biology.The neuroelectrophysiological methods have characteristics such as simplicity in operation and non-invasiveness,mainly including cortical auditory evoked potential(CAEP)based on electroencephalography(EEG),such as Pl-N1-P2 waves and mismatch negative(MMN),and auditory evoked field(AEF)based on magnetoencephalography(MEG).However,AEF is less applied due to its costly detection equipment,complex operation,and stringent environmental requirements.This article will review neuroelectrophysiological evaluation methods and the research progress in auditory cortex function.
