Brain Control for Artificial Limbs

摘要

When Jan Scheuermann grasped a chocolate bar and raised it to her mouth last year, it was a neuroscience breakthrough. Scheuermann, who has lost the movement of her limbs due to a degenerative spinal condition, was piloting a mechanical arm connected to her brain, using her thoughts to replicate natural motion. It was also a triumph for Andrew Schwartz, a neurophysiologist at the University of Pittsburgh, who's spent three decades mapping the connections between the brain and the body.
