So, what is a cochlear implant?
Deep in your ear is a remarkable pea-sized structure called the cochlea. The cochlea is fully developed at birth. Tiny, delicate hair cells in the cochlea communicate sound signals to your brain, allowing you to hear different pitches and sounds. If these delicate cells are damaged, you can lose some or all of your ability to hear.
Cochlear implants are designed to compensate for the damaged cells, helping to restore your ability to perceive and understand sounds. A cochlear implant works by bypassing the damaged part of the ear and sending sound signals directly to the hearing nerve.
1. The external sound processor captures sounds, then filters and processes the sounds.
2. The sound processor translates the filtered sounds into digital information, which is then transmitted to the internal implant.
3. The internal implant converts the digital information into electrical signals, and sends them to a tiny, delicate curl of electrodes that sits gently inside the cochlea.
4. The electrical signals from the electrodes stimulate the hearing nerve, bypassing the damaged cells that cause hearing loss, allowing the brain to perceive sound.

Seth will be getting the Nucleus 5. Now our biggest dilema, what color? The outside wires and processor come in five colors: black, white, beige, brown, and charcoal. I think we'll get the wiring in brown and the processor in beige.
This is what will be outside his head or what you see. The processor is worn behind the ear, just like a hearing aid. The wire (coil) attaches to the head by a magnet!
This is what will be underneath his scalp and muscle. See the magnet in the circle where the outside coil will attach?
And this is what it will look like.
