He S, et al. - Experts sought to investigate the responsiveness of the cochlear nerve (CN) to a single biphasic-electrical pulse in implanted children with cochlear nerve deficiency (CND). They also drew a comparison of their results with those measured in implanted children with normal-size CNs. They found that the functional status of the CN varied along the length of the cochlea, in children with CND. Children with CND demonstrated reduced CN responsiveness to electrical stimuli when compared to children with normal-size CNs. In children with CND, the prolonged CN absolute refractory period could at least partially, account for the observed benefit of using relatively slow pulse rate in these subjects.
