Sleep: De-cluttering the brain

I love it when research shows that the way our bodies work reflect the way man made things work. It implies we're along the right track and also that this knowledge of ours will then be useful to us in other ways in time.

an article describing the sleep deprived brain as a brain full of wool implies that the brai, while constantly maintaining and improving itself according to daily needs has a constant stack of work left to do. Much of this work can only be done in a rested or resting state. Thus without sleep this backlog builds up and up until eventually it effects our ability to perform and do basic daily things.
