Microchip technology rapidly identifies compounds for regrowing nerves in live animals

Scientists have long sought the ability to regenerate nerve cells, or neurones, which could offer a new way to treat spinal-cord damage as well as neurological diseases such as Alzheimer's or Parkinson's. Many chemicals can regenerate neurones grown in Petri dishes in the lab, but it's difficult and time-consuming to identify those chemicals that work in live animals, which is critical for developing drugs for humans...
