As someone who is legally blind in my right eye, this story is very interesting.
A new study published in npj Regenerative Medicine shows that eyes, and probably other sensory organs, don’t have to be attached directly to the brain in order to function properly. What’s more, a drug typically used to treat migraine headaches, Zolmitriptan, boosts the body’s ability to foster nerve growth—at least in amphibians. Previous work has shown that functional eyes could be grafted in blinded tadpoles, but the new research shows its possible to use drugs to improve the efficiency of the process. The researchers are hopeful the finding could improve the success of biological implants in humans.
