Researchers reconstruct 3-D hand movement using brain signals

Researchers have successfully reconstructed 3-D hand motions from brain signals recorded in a non-invasive way, according to a study in the March 3 issue of The Journal of Neuroscience. 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.
