Neural response measures in CI patients

Johan Frijns

A cochlear implant (CI) stimulates the auditory nerve and gives rise to a sensation of sound. In this way deaf and hearing-impaired people are able to hear again. In the speech processor the acoustic signal is converted to an electric stimulation paradigm for the auditory nerve. The optimal settings of this paradigm depend on many parameters that are often determined by subjective responses of the CI user. Implants nowadays have the opportunity to measure the response of the auditory nerve. By correlating these (objective) measures to the (subjective) responses of the CI user, we try to develop an objective method for fitting the processor.  Additionally improved or new tests are developed to be able to get insight in electrical and neural interaction. In collaboration with the TUDelft (Faculty EWI), the possibilities are investigated to improve the recording capabilities of implants.
