When Yadong Wang, a chemist by training, first ventured into nerve regeneration two years ago, he didn’t know that his peers would have considered him crazy.His idea was simple: Because neural circuits use electrical signals often conducted by neurotransmitters (chemical messengers) to communicate between the brain and the rest of the body, he could build neurotransmitters into the material used to repair a broken circuit. The neurotransmitters could coax the neurons in the damaged nerves to regrow and reconnect with their target organ. …
