BrainPort Remaps Sensory Input to Tongue
Neuroscientist Paul Bach-y-Rita's work on sensory substitution has spawned BrainPort, a sensory remapping unit that uses the tongue as sensory input interface. BrainPort uses the tongue to map the image picked up by a camera into discrete electrical points with up to 600 image points. BrainPort has also been used to correct balance in patients with vestibular dysfunction. See the facinating video on Wired Science:
