*slow clap for this dad*

They're for people who have trouble hearing I think. I knew a girl who had one and that's what she said.

Its an implant hearing aid, it bypasses the basically nonfuctional ear and passes the information directly to the brain. https://en.wikipedia.org/wiki/Cochlear_implant?wprov=sfia1

It's technical name is a cochlear implant it mimics the job of your inner ear parts.

After doing research on the cochlea/hair cells for a long time...I can never look at swirly ice cream the same again :\

Not at all, there is so much information we can learn by reading fiction stories. Just make sure that the information you've read is accurate and you're good to go!

It's implanted in the head

Technically there's a magnet implanted in her head- the cochlear implant's receiver attaches to that.

oh thank you
