The Mysteries of Sleep Explained

We know we need it. If we don't get it, we're cranky, have trouble concentrating, tend to overeat and are more likely to make mistakes.  Yet, with the crush of demanding schedules, bad habits, or sleep disturbances, we don't always get enough.

So what is happening during those precious hours when we're asleep?  Is it really a time of restoration for our brains?  And is it possible that it's more than that?

What happens in our brains while we're asleep is a question neuroscientist Penelope Lewis is trying to answer.

Lewis directs the Sleep and Memory Lab at the University of Manchester in England. In her new book, The Secret World of Sleep: The Surprising Science of the Mind at Rest, she discusses how sleep makes memory stronger, provides what she terms "spring cleaning" for the brain, and plays a role in depression.
