The Coclier Implant, a Device for Hearing Loss
The coclier implant is a device for people with hearing loss. It involves placing an array of electrodes in the coclia, where hair cells are responsible for transducing physical vibrations that make up sound waves. And if you have hearing laws that impairs that process, if those cells have died or something, then you can replace their action by electrically stimulating the nerve fibres they came into contact with. But you can't do it in anything remotely close to the way that the original hair cells would would have fired. The discovery has been really exciting in brain science: we have more plasticity than we probably appreciated.
