Schieber Lab

Dr. Schieber studies brain control movements of the body, translating our findings to advance brain-machine interface technology for restoration and repair of lost or damaged neurological function. A longstanding line of investigation explores control of fine finger movements, like those used in typing, playing a musical instrument, or performing delicate surgery. More recent work explores the combination of reaching, grasping, and manipulating. In both realms, we study how the brain controls a rather complex set of muscles to achieve the required movement.
