"The current distribution in the cochlea and coding of acoustic information"

(1) The current distribution in the cochlea:
Although cochlear implants are able to restore some auditory sensation, they are far from providing normal hearing. This project will provide for the first time fundamental data on the current path in the cochleae and will quantify changes of the current path that occur after neural degeneration.

(2) Coding of acoustic information:
For a cochlear implant user the speech signal has to be processed and encoded in electrical signals to be sent to the implanted electrode contact. This project will test a possible novel coding strategy that is based on a stochastic model (Hidden Markov Model, HMM) developed by the PI to describe the activity of a single auditory nerve fiber.
