Researchers Pave the Way for New Generation of Cochlear Implants

Cochlear implants today operate with varying degrees of success in different patients. While some facilitate the hearing of sounds like the rush of traffic or the crash of thunder, others provide even better hearing response such as detecting voice and understanding speech while still being unable to appreciate music.
Robin Davis, a professor in the Department of Cell Biology and Neuroscience at the university, says that his team’s work may provide for a dramatic improvement in such implants.
He says that the study’s findings are important for engineers and surgeons in designing new cochlear implants.
“The significance of our work lies in the fact that we can change an element in a very peripheral part of the sensory system that can have an impact all the way into the brain,” he said.
Cochlear implants, also known as “bionic ears”, are surgically inserted into the snail-shell shaped structure within the inner ear called the cochlea. Hair cells line the cochlea and convert acoustic signals into electrical signals that nerves then carry to the brain.
Davis says that sounds can be amplified with a hearing aid where some hair cells exist. But where the hair cells are missing or damaged, a condition generally associated with severe hearing impairment, an implant may be used to replace their function, he adds.
