Spread of Excitation (SoE) - a new method of assessment of auditory nerve function

摘要

To provide maximum benefit for the cochlear implant users the speech processor should be fitted to the patient's need. One of objective methods which could deliver important information for fitting is Neural Response Telemetry (NRT). This method helps to estimate an amplitude of electrical current that is required to elicit hearing sensation via cochlear implant. It is also possible to determine Spread of Excitation - the longitudinal spread of electrically evoked neural excitation in the cochlea, based on NRT results.
