One of the biggest medical challenges facing us today is how to treat damaged nerves on a human. There are many theories and ideas as to what we could do to regulate damaged nerves, but nothing substantial has yet to be found for human use. In a new study at Tufts University, researches took blind tadpoles and gave them a small molecule nerotransmitter drug. This drug caused the tadpoles to be able to process visual information, which otherwise would not have been possible. This is exciting because it can possibly be a first step towards similar types of treatment for humans. If we could fix broken nerves we could annihilate many of our modern medical dilemmas.
