Electrodes placed inside the cochlear receive the decoded signals. The 22 electrodes allow a range of different pitches to be detected. The electrodes stimulate the hearing receptors.
As many as 24 electrodes, depending on the type of the implant, stimulate the ganglion cells in the cochlea
22 electrodes are inserted into the cranium and are tested by stimulation to check auditory response.
In a cochlear implant, sound is picked up by a microphone then processed by a speech processor before being sent as electrical signals to electrodes in the cochlea. These electrodes stimulate the auditory nerve fibers, which in turn send the signals to the brain for interpretation as sound.
Doctor Graeme Clark invented the Cochlear implant (bionic ear) at the University of Melbourne.

Cochlear Implant
The cochlear implant replaces the function of the damaged or missing hair cells in the cochlea, which are responsible for converting sound vibrations into electrical signals that can be interpreted by the brain.
Cochlear implant. A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing. The cochlear implant is often referred to as a bionic ear.
