Bsa cochlear microphonic protocol
WebCochlea Potential. The cochlear microphonic and the summating potential (SP) are generated by the hair cells of the organ of Corti, whereas the compound action potential (AP) of the auditory nerve represents the summed synchronized response of many individual nerve fibers.
