Rehabilitative device bridges the gap between stroke victims’ brains and hands

We?ve recently seen rehabilitative systems in which stroke victims use their thoughts either to move animated images of their paralyzed limbs, or to activate robotic devices that guide their limbs through the desired movements. Scientists at the University of Wisconsin-Madison, however, have just announced an alternative approach. Their device acts as an intermediary between the brain and a non-responsive hand, receiving signals from the one and transmitting them to the other.
