They can't reproduce, but mature neurons can grow. Indeed, for more than a century, neurologists have been able to restore at least partial function to severed peripheral nerve networks through neuronal transplantation. But the CNS has proved more recalcitrant: there, scar tissue and a complex molecular brew stymie the efforts of damaged axons to sprout new fibers and restore old connections.
