Staying up all night harms women's working memory

On February 3, 2018, Posted by , In Buzz, By ,,,,, , With No Comments

Most of us have experienced the “brain fog” that comes after a bad night’s sleep. A new study, however, reveals that when it comes to the effect of sleep deprivation on working memory, women fare worse than men. The working memory of women, but not men, is negatively impacted by…

Sleep apnea in children impairs memory consolidation

On November 9, 2017, Posted by , In Buzz, By ,,,,, , With No Comments

New research sheds light on sleep apnea in children. A new study examined how obstructive sleep apnea in children may interfere with memory consolidation, and it also uncovered a potential method of predicting the level of disruption caused by the associated sleep loss. Over the years, science has delved into the nature and function of sleep. Although there…

Sleep's role in memory consolidation unpicked

On October 3, 2017, Posted by , In Buzz, By ,,,, , With No Comments

New research has started to unpick the mechanism that allows sleep to enhance memory consolidation. Sleep spindles, a type of brain activity recorded during stage two of sleep, has repeatedly been associated with improving brain plasticity and consolidating memory. Scientists are now drawing closer to explaining the mechanism behind this…

Finding traces of memory processing during sleep

On May 18, 2017, Posted by , In Buzz, By ,,,,, , With No Comments

Sleep helps us to retain the information that we have learned during the day. We know from animal experiments that new memories are reactivated during sleep. The brain replays previous experience while we sleep – and this replay strengthens memories overnight. Up to now, it was hard to demonstrate such…

'Pink noise' boosts deep sleep, memory for older adults

On April 30, 2017, Posted by , In Buzz, By ,,,,,,, , With No Comments

As we age, our quality of sleep declines. Researchers believe that this may contribute to later-life memory loss. New research, however, suggests that there may be a simple solution to this problem: “pink noise.” Researchers say that pink noise may help to improve deep sleep quality and memory for older…

How does lack of sleep impair memory formation? Study sheds light

On April 10, 2017, Posted by , In Buzz, By ,,,,,,, , With No Comments

Sleep is known to play a key role in learning and memory formation, but what happens to these important brain functions when we fail to get enough sleep? Researchers from the University of Michigan provide some answers with their new study. Researchers suggest that sleep deprivation disrupts the rhythm of…

How sleep deprivation harms memory

On August 25, 2016, Posted by , In Buzz, By ,,, , With No Comments

Researchers from the Universities of Groningen (Netherlands) and Pennsylvania have discovered a piece in the puzzle of how sleep deprivation negatively affects memory. For the first time, a study in mice, to be published in the journal eLife, shows that five hours of sleep deprivation leads to…

Researchers find possible missing link between sleep and improved memory

On June 16, 2016, Posted by , In Buzz, By ,,,,,,,, , With No Comments

A team of sleep researchers at the University of California, Riverside, led by psychology professor Sara C. Mednick, has found that the autonomic nervous system, which is responsible for control of bodily functions not consciously directed (such as breathing, heartbeat, and digestive processes) plays a role in promoting memory…

Mechanism through which sleep improves memory uncovered

On June 16, 2016, Posted by , In Buzz, By ,,,,, , With No Comments

Sleep researchers agree that sleep plays an important role in moving information from short- to long-term memory; however, attempts to uncover the underlying processes have yielded conflicting results. Now, for the first time, new research reveals that autonomic nervous system activity during rapid eye movement sleep appears to play…

Mimicking deep sleep brain activity improves memory

On May 27, 2016, Posted by , In Buzz, By ,,,,,, , With No Comments

It is not surprising that a good night’s sleep improves our ability to remember what we learned during the day. Now, researchers at the RIKEN Brain Science Institute in Japan have discovered a brain circuit that governs how certain memories are consolidated in the brain during sleep. Published in…
