I recently had a cochlear implant and am trying to explain exactly what they did to some dear friends. As I understand it they hollowed out a pocket in my skull and inserted a receiver and a magnet and ran a wire down under the skin to the cochlea of my left ear. This wire brings electrical impulses that the cochlea must be able to interpret as sound, this takes time and learning. The function of the receiver is also to transmit to a receiver in a hearing aid in my right ear. The hearing aid in my right ear requires no learning as it puts out understandable sound. Is this correct?
