The Assessment of Electrode-Neuron Interface (ENI) in Cochlear Implant Users

Abstract

The electrode-neuron interface (ENI) plays an important in the outcome with cochlear implants as all cochlear implant-mediated signals should pass through this interface. Telemetry has enabled researchers to study factors affecting the quality and integrity of the interface. These factors may influence electrodes, the path between electrodes and auditory neurons, and spiral ganglion neuron survival. Promising studies on animals regarding such factors have opened new possibilities to identify cochlear implant channels with poor electrode-neuron interface. The results of these studies and similar research on human with focus were discussed in this chapter.
