1	Snail Tales: Cochlear Implants By Sharaine J. Rawlinson, MSW Materials Development Specialist WROCC California State University Northridge
2	Overview Cochlear Implants are referred to as auditory prosthesis. They are: for people who cannot benefit from hearing aids controversial available in different models a personal choice
3	Expectations CIs will not restore hearing to “normal” Benefits vary among individuals Some CI users only gain knowledge of environmental sound Others gain ability to use telephone and hear music CIs do not make a deaf person hearing!
4	How Cochlear Implants Work Cochlear implants are designed to by-pass cochlear hair cells which are non-functioning and provide direct stimulation to the auditory nerve.
5	Specifically … The microphone picks up sounds and sends them to the processor The processor then selects and codes sounds which produce useful speech, music, etc. From the processor, sounds are transmitted through the skin to the receiver/stimulator via the magnetic headset
6	From here … The codes are then converted to electrical signals which activate the electrode arrays The electrodes then stimulate the auditory nerve where the brain recognizes the electrical signals as sounds.

13	Aural Rehabilitation Following hook-up, many people participate in aural rehabilitation Aural rehabilitation consists of learning to listen, training the brain to decipher individual sounds, followed by more and more complex sounds as one’s listening skills improve
14	The Controversy Surrounding CIs NAD’s former position on implanting children AG Bell’s position on sign language vs. oral Are children who receive implants stolen from the Deaf World? Are children who have implants being “scarred for life”?
15	The Controversy Continued … Do adults who receive cochlear implants risk alienation by their deaf friends and colleagues? Interpreters as critics. Is the corporate world creating implants simply for the money? Are doctors ignoring cultural aspects of deafness?

17	What Can You Do For These Students? Remember, they are NOT hearing people! If the student signs, always sign with them even if they appear to comprehend your spoken voice Use Assistive Listening Devices Make sure the student is looking at you when you talk to them
18	What Can You Do For These Students? Acknowledge that cochlear implants are here to stay and that these students should be included in activities, not shunned Assist the student with a CI in learning communication skills that will enable them to communicate with other students who do not have a CI
