Wake-sleep Patterns Affect Brain Synapses During Adolescence
2011-10-10 04:39:10

An ongoing lack of sleep during adolescence could lead to more than dragging, foggy teens, a University of Wisconsin-Madison study suggests. Researchers have found that short-term sleep restriction in adolescent mice prevented the balanced growth and depletion of brain synapses, connections between nerve cells where communication occurs. "One possible implication of our study is that if you lose too much sleep during adolescence, especially chronically, there may be lasting consequences...

Just like human teenagers, fruit flies that spend a day buzzing around the "fly mall" with their companions need more sleep. That's because the environment makes their brain circuits grow dense new synapses and they need sleep to dial back the energy needs of their stimulated brains, according to a new study by UW- Madison sleep researchers. Researchers saw this increase in the number of synapses -- the junctions between nerve cells where electrical or chemical signals pass to the next cell...

Burning the candle at both ends for a week may take an even bigger toll than you thought. Researchers at the University of Wisconsin-Madison have found that five nights of restricted sleep--four hours a night--affect the brain in a way similar to that seen after acute total sleep deprivation. The new study in rats, appearing in the current online edition of the Proceedings of the National Academy of Sciences, adds to the growing evidence scientists are accumulating about the negative effects...

 If you've ever been sleep-deprived, you know the feeling that your brain is full of wool.Now, a study published in the April 3 edition of the journal Science has molecular and structural evidence of that woolly feeling "” proteins that build up in the brains of sleep-deprived fruit flies and drop to lower levels in the brains of the well-rested. The proteins are located in the synapses, those specialized parts of neurons that allow brain cells to communicate with other...

MADISON "“ Most people know it from experience: After so many hours of being awake, your brain feels unable to absorb any more -- and several hours of sleep will refresh it. Now new research from the University of Wisconsin School of Medicine and Public Health clarifies this phenomenon, supporting the idea that sleep plays a critical role in the brain's ability to change in response to its environment. This ability, called plasticity, is at the heart of learning. Reporting in the Jan....
