Hughes, who coordinates a cochlear implant program and cochlear implant research laboratory at a hospital and teaches special education and communication disorders at the U. of Nebraska-Lincoln, offers audiology graduate students and audiologists a guide to objective measures in cochlear implants, with information on measurements and clinical uses for each. She discusses the basic science, including the anatomy of hearing loss, principles of electrical stimulation of the auditory system, parts and functions of a cochlear implant, past and present devices, candidacy, and signal delivery with cochlear implants; nonphysiological objective measures, including electrode impedance, electrical field potentials, and averaged electrode voltages; and physiological measures: electrically evoked stapedial reflexes, compound action potentials, auditory brainstem response, auditory middle latency response, and auditory cortical potentials.
