Building the musical muscle Charles Limb on

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 2011, Limb reviews the state of the art and the way forward. (Recorded at TEDMED 2011, October 2011, in San Diego, California. Duration: 16:00)
