How the brain controls sleep

Neuroscientists have discovered a brain circuit that can trigger small regions of the brain to fall asleep or become less alert, while the rest of the brain remains awake. The researchers believe this may help the brain consolidate new memories by coordinating slow waves between different parts of the brain, allowing them to share information more easily.
