How Can The Cochlear Implant Help?
A4. The cochlear implant conveys weak electric stimuli to the vicinity of the auditory nerve. The electric stimulus activates the nerve, which then transmits a signal to the brain. The brain recognizes this signal and we experience this as “hearing”. The cochlear implant has the same function as the hair cells, in that it transforms sound into an electric current that stimulates the auditory nerve. Nevertheless, the result is not the same as normal hearing.
