 Well, new hope today for those who have lost a limb. Scientists have made new strides in prosthetic limbs and how they actually interact with the brain. When you see someone walking with an artificial limb, they don't have full neural control over it. Instead, they're likely using a robotic controller to move the prosthesis at a gait that's been pre-programmed into it. But researchers at MIT are trying a new procedure that through surgical amputation reconnects muscles to the body's own nervous system.
