U.S.-led research is providing strong support for the idea that one of the key functions of sleep is the consolidation of memories.University of Pennsylvania School of Medicine researchers say although sleep is thought to facilitate memory and learning, the molecular links between sleep and synaptic plasticity aren't well understood. Ocular dominance plasticity -- in which one eye can become dominant if the other eye is blocked -- is a classic model of experience-dependent cortical plasticity that allows scientists to follow specific changes in the visual cortex in response to the occlusion of one eye.
"We have shown that ODP is consolidated by sleep," said senior study author Assistant Professor Marcos Frank.
Frank and colleagues performed a series of experiments designed to test the hypothesis and found sleep consolidates ODP primarily by strengthening cortical responses to stimulation of the non-deprived eye. They discovered certain receptors and proteins mediated intracellular cascades and were critical components of the cellular machinery required for sleep-dependent consolidation of ODP, and their activation during sleep promoted synaptic strengthening.

pjacobs51 your are about right there..de-fragging and re-alignment of a day of scrambled functions for some people..where the files of the mind are not quite put back in order..and need to be re-stored to their former places before rest can come.
The brain is the messenger for these functions along with the automatic response systems and because it does not have the same physical functions of the complex(body)then its life is always in service all the time without the usual rest.
Memory does not live in the brain as most people think but resides in the human aura..that is why sometimes when you meet someone new..you can gain a glimpse of their history..or how a clairvoyant can read your life history so well...
Memory of the automatic response intelligences in us work through-out the brain as part of its life cycle but we do not directly control these aspects of us..thank God... - 12 months ago

It's the consolidation of everything! One big teeming ocean, down to those bizarre deep sea creatures that make their own light. Sleep is a genius brain manager. Underappreciated and amazing.

This sounds like when you sleep your are also defraging your hard drive. I wonder, since sleep consolidates your ODP, does it also figure out if your right or left handed?
