Charles Limb: Building the musical muscle

Charles Limb: Building the musical muscle
Charles Limb performs cochlear implantation, a surgery that treats  hearing loss and can restore the ability to hear speech. But as a  musician too, Limb thinks about what the implants lack: They don't let  you fully experience music yet. (There's a hair-raising example.) At  TEDMED, Limb reviews the state of the art and the way forward.
