Abstract
A method and apparatus for diagnosing the extent of survival of the peripheral sensori-neural elements within the inner ear of a patient by stimulating the patient with one or more pair of electrical stimulus signals having a known amplitude and inter-signal delay, and by measuring the electrical activity within the nervous system of the patient which results from these stimulus signals and comparing the activity which results from the second stimulus signal with the activity which results from the first stimulus signal.
