USING INTERACTION TO MEASURE NEURAL EXCITATION

摘要

Neural survival related to a cochlear implant can be assessed by determining stimulus efficacy for both focused and unfocused stimulation at a plurality of locations adjacent said nerve tissue; and comparing stimulus efficacy for both said focused and unfocused stimulation at said plurality of locations to determine a measure of neural survival. In particular small differences in effects produced by unfocused and focused stimulation at each of the locations tends to indicate good survival at those locations and conversely large differences in effects of focused and unfocused stimulation at a given location indicate poor survival at that location.
