Study reveals as we sleep, cerebrospinal fluid pulses in the brain in rhythmic patterns.... Read More...
non-REM sleep
Key to learning and forgetting identified in sleeping brain
Using optogenetics to dampen delta waves of rats during sleep resulted in weaker memory reactivation and promoted forgetting. The findings could have significant implications for treating PTSD in humans.... Read More...
Not All Sleep is Equal When it Comes to Cleaning the Brain
Study reinforces and explains the links between sleep deprivation and neurodegenerative diseases, researchers say.... Read More...
Rocking Improves Sleep and Memory in Both People and Mice
A new study reveals people fall asleep faster when being rocked. Additionally, they showed improvements in memory consolidation and spent more time in non-REM sleep.... Read More...
Decreased Deep Sleep Linked to Early Alzheimer’s Disease
A new study links poor sleep quality in older adults with elevated levels of tau, a protein associated with Alzheimer's disease. Researchers report poor sleep quality later in life may be associated with declining brain health and may be an early indicator of Alzheimer's disease.... Read More...
Genes that Regulate How Much We Dream
A new study identifies two genes which regulate how much we dream. The genes, Chrm1 and Chrm3, play a key role in regulating REM sleep and function in different ways.... Read More...
Skills and Learning Improved by Closed Loop Electrical Brain Stimulation During Sleep
Researchers report transcranial alternating current stimulation applied during sleep can help accelerate learning, memory and skill acquisition.... Read More...
How REM and Non-REM Sleep May Work Together to Help Solve Problems
Researchers have created a new model that may help explain how different sleep patterns may help us to solve problems. The study reveals non-REM sleep helps us categorize information, where as REM sleep helps us to draw unexpected connections between information we have been exposed to.... Read More...
Memories Can Be Decoded from Brain Waves During Sleep
Sleep spindles assist with the processing of relevant memories during sleep and help boost memory consolidation, researchers report.... Read More...
First Look at Pupil Size in Sleeping Mice Yields Surprises
Researchers report the size of the pupil fluctuates during sleep. The findings may indicate that pupil size can indicate specific sleep states.... Read More...
Wrist Worn Gadget Allows Researchers to Capture Real Life Sleep
A simple actimeter device is helping researchers better understand sleep duration and quality in humans.... Read More...
Brain Still ‘Connected’ During Non-REM Sleep
Contrary to a popular theory, researchers discover the brain remains connected during non-REM sleep. The study reports not all forms of communication within the cerebral cortex are disrupted during this sleep phase.... Read More...
