ABSTRACT:
This invention relates to a method and apparatus for obtaining and registering the Electrical Cochlear Response (“ECR”). Particularly, the ECR refers to the electrical activity of the auditory nerve and the intracochlear residual tissue located in the neighborhood of an intracochlear stimulation electrode, when an external sound is presented to a Cochlear Implant user, human or animal. Applicants recognize that an ECR can be thought of as a far-field electrical potential registered on the scalp of an implanted patient. Applicants, through their method and apparatus, can extract that potential from the patient's spontaneous electroencephalographic activity (EEG) and measure it by using an averaging algorithm. The Electrical Cochlear Response can be applied for adaptation, calibration, performance evaluation and failure detection of the Cochlear Implant of the implanted patient. Also Applicants' method can be applied to estimate the audiometric thresholds of the Cochlear Implant even without the implanted patient's knowledge.
