Blind tadpoles were able to process visual information from eyes grafted onto their tails after being treated with a small molecule neurotransmitter drug that augmented innervation, integration, and function of the transplanted organs. The work, which used a pharmacological reagent already approved for use in humans, provides a potential road map for promoting innervation -- the supply of nerves to a body part -- in regenerative medicine.
