Why we need sleep to process and develop memories

Did you ever argue with your mother when she told you to get some sleep instead of pulling an all-nighter to study for a major exam? If you did, you should apologize to her, even now — years later — because she was right!. Scientists are just now beginning to understand why.

Research findings published by Marcos Frank, Ph.D., an assistant professor of Neuroscience at the University of Pennsylvania School of Medicine, describe how cellular changes in the sleseping brain promote the formation of memories.

Interesting Apnea Statistics
~~ Apnea in United States ~~

As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the U.S. population
was 306,340,710. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 21,443,850 apneics in the U.S.

~~ Apnea around the world ~~

As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the world population
was 6,777,286,604. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 474,410,062 apneics in the world.
