This mind-controlled prosthetic arm can control individual finger movements

Researchers at Johns Hopkins have just detailed a proof-of-concept feat that represents a significant leap in the world of prosthesis. In the experiment a young man who wasn’t missing any limbs but required brain mapping to pinpoint the origin of his seizures underwent a procedure that aimed to chart specific areas of the brain that “lit up” when he moved his fingers on command. The procedure pinpointed the exact location of his brain that controlled finger movement befor
