The Biomechanics of a Cochlear Implant Hearing Restoration

Quick fact

A cochlear implant can restore hearing for people with severe sensorineural hearing loss by directly electrically stimulating the auditory nerve, bypassing the damaged hair cells entirely. Some recipients can understand speech without lip-reading, a feat that underscores the brain's remarkable ability to adapt to a completely new sensory input.

Why this is interesting

You know how a piano has low notes on the left and high notes on the right? Your inner ear does something similar—but with tiny hair cells that can break. What if we could replace those hairs with a wire?
