What is Cochlear Implantation

Chapter 40
Handbook of Research on Natural Computing for Optimization Problems
The use of cochlear implants for hearing rehabilitation of deaf individuals is widespread all over the world with more than 100,000 users in the world today. The cochlear implant is an electronic device that replaces the function of the damaged or absent hair cells in the organ of Corti in the cochlea. An electrode array, which is inserted in the cochlea during a delicate microsurgical procedure, stimulates electrically the remaining auditory nerve fibres with codified sound information. The implant converts the incoming converted sound signal into electric signals that reach the cochlear nerve through an array of electrodes ranging from 12 to 22 depending on the implant model and brand. These electric signals stimulate the nerve in a way that simulates the normal function of the cochlea. Cochlear implants are not hearing aids; they operate when patients face complete hearing loss.

Abstract
This chapter focuses on the framework of non-deterministic Brain Computer Interfaces within the context of Human Computer Interaction. A very special subgroup of these interfaces, emerging from the world of hearing loss, comprises the Cochlear Implants that affirmatively expose direct manipulation techniques. Short and long memory experiments with musical exploitation can prove shortcomings in inner-knowledge handling and provide understanding of how the language mechanism provides steady, un-biased speech. A model and a protocol for parameterizing sustainable aural communication skills are presented.
