Researchers from Johns Hopkins University have developed a new brain-machine interface (BMI) that enables patients to move the individual fingers of a prosthetic hand using their brain signals. Reporting their progress in the Journal of Neural Engineering, the team describe how their test subject was able to operate the device with no previous training.
