Electrically evoked compound action potentials recorded from subjects who use the nucleus CI24M device.

The ability to directly measure the response to a pulse with the NRT opens the possibility of using this system to characterize the responses to more complex stimuli. An example is the responses to constant-amplitude pulse trains. With further changes in the software that controls the implant, it may be possible to characterize the responses to modulated pulse trains or other stimuli that better approximate the type of stimuli that are normally used with a cochlear implant speech processor.
