Abstract:
1. A system for analyzing operation of a cochlear stimulation system implanted in a patient, the system comprising: a sound generating system for generating a sound stimulus signal to elicit operation of the cochlear stimulation system; an electrical cochlear response (“ECR”) detection system to detect an ECR waveform in a plurality of electro encephalographic (EEG) signals received from the patient using surface electrodes, the EEG signals being generated in response to the sound stimulus signal; and an ECR waveform processor configured to receive the EEG signals and to process the EEG signals to generate measured responses at selected frequencies and sound intensities, the ECR waveform processor being configured to facilitate analysis of the measured responses to detect ECR waveforms in the measured responses, the ECR waveform being indicative of operation of the cochlear stimulation system.
