Lights help with Brain.

April 12th, 2010 · No Comments · Biology

Scientists believe that they might have found certain lights to turn off brain cells. Not only would the lights be able to turn off the cells of the brain, they might be able to fix brain disorders. “Silencing different sets of neurons with different colors of light allows us to understand how they work together [...]
