Now, researchers seem to have found it by coincidence while studying an epileptic patient—and used electronic brain stimulation to… » 7/06/14 9:00am 7/06/14 9:00am

Scientists Cured Paralysis in Mice with Stem Cells and Lasers

This is wild. Chasing the elusive dream of curing paralysis, a team of scientists used stem cells and optogenetics to circumvent the central motor system of lab mice whose nerves had been cut. This enabled them to blast individual motor neurons with a laser, triggering movement in the legs of the mice. » 4/03/14 6:45pm 4/03/14 6:45pm

Looking at Orange Light Is Like Drinking a Cup of Coffee
