When you go to sleep ... your brain goes on a cleaning spree!

Researchers at the University of Rochester Medical Center studied mice to learn what happens in the brain during sleep.

They injected brain plaque into each mouse, then kept some awake and allowed others to sleep.

They found the sleeping mice cleared the plaque from their brains faster than those who stayed awake. researchers say it is logical to assume a similar process happens in humans.

The researchers also found brain cells shrink during sleep -- making room for junk to pass through and leave the brain.
