Sleep May Help Brain Flush Out Toxins
2013-10-17 15:54:09

[ Watch The Video: Brain Opens up the Pipes During Sleep ] NIH/National Institute of Neurological Disorders and Stroke A good night's rest may literally clear the mind. Using mice, researchers showed for the first time that the space between brain cells may increase during sleep, allowing the brain to flush out toxins that build up during waking hours. These results suggest a new role for sleep in health and disease. The study was funded by the National Institute of Neurological...

WATCH VIDEO: [Forebrain Engraftment In Mice] redOrbit Staff & Wire Reports - Your Universe Online A group of non-neural cells found in the human central nervous system may be more essential to the complexity of our brains than previously believed, according to new research published in Thursday´s edition of the journal Cell Stem Cell. A team led by Steven A. Goldman and Maiken Nedergaard of the University of Rochester Medical Center´s (URMC) Center for Translational...

Cleansing System Inside Brain Drains Waste Products
2012-08-16 12:47:44

Connie K. Ho for redOrbit.com — Your Universe Online Researchers recently discovered a cleansing system in the brain with a new imaging technique. Neuroscientists at the University of Rochester Medical Center found a system that can drain the waste from the brain; it was previously unrecognized by scientists. The system is highly organized and is designed with a series of pipes that depend on the brain´s blood vessels, providing the same function in the brain as the...

A type of cell plentiful in the brain, long considered mainly the stuff that holds the brain together and oft-overlooked by scientists more interested in flashier cells known as neurons, wields more power in the brain than has been realized, according to new research published today in Science Signaling. Neuroscientists at the University of Rochester Medical Center report that astrocytes are crucial for creating the proper environment for our brains to work. The team found that the cells...

A type of brain cell that was long overlooked by researchers embodies one of very few ways in which the human brain differs fundamentally from that of a mouse or rat, according to researchers who published their findings as the cover story in the March 11 issue of the Journal of Neuroscience.Scientists at the University of Rochester Medical Center found that human astrocytes, cells that were long thought simply to support flashier brain cells known as neurons that send electrical signals, are...

Star-shaped brain cells that are often overlooked by doctors and scientists as mere support cells appear to play a key role in the development of epilepsy, researchers say in a study published on-line August 14 in Nature Medicine. It's one of the first times scientists have produced firm evidence implicating the cells, known as astrocytes, in a common human disease. Scientists found that astrocytes can serve as ground zero in the brain, setting off a harmful cascade of electrical activity in...
