Researchers have successfully reconstructed 3-D hand motions from brain signals recorded in a non-invasive way. This finding uses a technique that may open new doors for portable brain-computer interface systems. Such a non-invasive system could potentially operate a robotic arm or motorized wheelchair -- a huge advance for people with disabilities or paralysis.
