Experimental Hearing Implant Succeeds in Registering Brain Waves

A cochlear implant enables people with severe hearing loss to hear again. An audiologist adjusts the device based on the user’s input, but this is not always easy. Think of children who are born deaf or elderly people with dementia. They have more difficulty assessing and communicating how well they hear the sounds, resulting in an implant that is not optimally tuned to their situation.
