After A Good Night's Sleep Brain Cells Are Ready To Learn

Neuroscientist Chiara Cirelli at the University of Wisconsin-Madison and others believe that a good night's sleep helps us learn more the next day. In this image on top, the brain of a sleep-deprived fly glows orange because of Bruchpilot, a communication protein between brain cells. These bright orange brain areas are associated with learning. On the bottom, a well-rested fly shows lower levels of Bruchpilot, which might make the fly ready to learn after a good night's rest.
