Show Notes
When Brandon Prestwood’s left hand was caught in an industrial conveyor belt 10 years ago, he lost his hand and forearm. Scientists are unraveling the science of touch by trying to tap into the human nervous system and re-create the sensation for people like Prestwood. After an experimental surgery, Prestwood’s prosthetic arm was upgraded with a rudimentary sense of touch—a major development in technology that could bring us all a little closer together.
