Abstract

Electrical stimulation of the auditory nerve has been used as a treatment for sensory hearing loss for approximately 30 years. The typical cochlear implant candidate has sensorineural hearing loss, suggesting a lack of functional hair cells in the cochlea. The electrical fields produced by a cochlear implant directly excite auditory nerve fibers to elicit a hearing sensation. While the average performance with prosthetic devices has continued to improve over the years, there remains significant variation in the performance of individuals using the same implant design. Understanding the biophysical mechanisms of electrical stimulation and the response properties of the auditory nerve therefore can have considerable practical importance. Such information could lead to better designs of auditory prostheses, development of stimuli that could improve information transfer with current devices, and improved clinical procedures for fitting the device and assessing neurophysiological status.
