Sleep well at night turned out to cleanse our minds. By using mice as experimental animals, the scientists showed that the spaces between brain cells develop during sleep, the brain could rid of Toxins which formed during our active.
These findings suggest a new role of sleep for health and disease. "Sleeping change the structure of brain cell. The organs seem to be in completely different conditions," said Maiken Nedergaard, director of the Center for Translational Neuromedicine at the University of Rochester Medical Center in New York, who led the study.
For centuries, the scientists are trying to find out why humans need sleep and how it affects to the brain. Not long ago the scientists learned that sleep is important for memory store. In this study, Nedergaard discovered that during sleep the brain rid itself of toxic molecules.

The results that published in the Science journal suggests that during we're slept, a pipe system that called glymphatic system (a waste clearance pathway in the central nervous system (CNS) of mammals) open and let the liquid flow quickly penetrate to the brain. The system that helps control the flow of cerebrospinal fluid (CSF), the clear liquid that surrounds the brain and spinal cord.
"The findings of Nedergaard and his team's, show the importance of networks in normal brain function," said Roderick Corriveau, Programs Director at the National Institute of Neurological Disorders and Stroke (NINDS), as reported by the NIH website, on October 17, 2013.
In the study, researchers injected dye into the mice's CSF and observe how the fluid flow to the whole brain while monitoring the electrical activity of the brain. The fluid flows faster when the rat did not realize, either sleeping or sedated. Instead, the liquid barely moves when the rats in conscious state. *** [EKA | FROM VARIOUS SOURCES | NIH | NINDS | SCIENCEDAILY | TJANDRA DEWI | KORAN TEMPO 4381]
