The human Hearing sense The outer ear picks up the sound vibrations The Sound vibrations are directed to the middle ear by the ear channel

The human Hearing sense Ossicular Chain The Ear drum sets the Ossicular chain in motion The Ossicular chain in its turn sets the Perilymph (Fluid in the cochlear) in the cochlear in motion

The human Hearing sense The Mechanical vibrations are converted to the electrical pulses by the hair cells The electrical pulses are sent to the auditory cortex by the auditory nerves

Cochlear Implant Some facts about the Cochlear Implant: Around 1790 Alessandro Volta experimentally discovered that electrical stimulation in the auditory system can create a perception of sound. “ It is like a thick boiling soup“, He said. André Djourno performs the first cochlear implantation in France, Dr. Michelson's patents and device are thought as the first cochlear implants. Alessandro Volta André Djourno

Cochlear Implant A cochlear implant consists of two parts: The sound processor The implant A flexible electrode array is inserted into the entire cochlear

Cochlear Implant The sound vibrations are converted to electrical signals and transmitted through the skin into the implant via the coil. The implant creates electrical pulses from the received signals and sends them to Auditory Cortex via Cochlear and auditory nerves.
