A specific brain activity pattern for dreaming

On April 12, 2017, Posted by , In Buzz, By ,,,, , With No Comments

A specific pattern of activity changes within a particular brain region can indicate when a person experiences a dream during both rapid eye movement (REM) sleep and non-REM (NREM) sleep, reports a paper published online in Nature Neuroscience. The study challenges the current understanding of the pattern of brain…

Specific brain regions, including those involved in awareness of self and tendency to ruminate, show altered activity in patients with insomnia when compared to good sleepers, according to a new study by researchers at the University of Pittsburgh School of Medicine published in the journal SLEEP. In…

Sleeping brain's complex activity mimicked by simple model

On September 3, 2016, Posted by , In Buzz, By ,,,,,, , With No Comments

New mathematical model could improve understanding of memory consolidation during deep sleep. Researchers have built and tested a new mathematical model that successfully reproduces complex brain activity during deep sleep, according to a study published in PLOS Computational Biology. Recent research has shown that…

Transcranial magnetic stimulation revealed differences between brain activity of people who dream and people who do not dream

Measurements demonstrated that the brain activity of people who dream during NREM sleep, compared to people who do not dream, is closer to the brain activity of awake people. Researchers from Aalto University and the University of Wisconsin utilised a TMS-EEG device, which combines transcranial magnetic stimulation…

Mimicking deep sleep brain activity improves memory

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…

Brain activity of nematodes seeking food offers new view on sleep

On March 10, 2016, Posted by , In Buzz, By ,,,,,,, , With No Comments

University of Oregon researchers say the neural circuitry of foraging behavior is similar to fragmentation in human sleep disorders. If you have trouble sleeping, the neurons in your brain may be firing like those in roundworms randomly seeking food in the absence of clues, says University of Oregon…

Best to sleep on it: brain activity patterns during sleep consolidate memory

On February 20, 2016, Posted by , In Buzz, By ,,,,,,, , With No Comments

Why does sleeping on it help? This is the question tackled by new research at the University of Bristol, which reveals how brain activity during sleep sorts through the huge number of experiences we encounter every day, filing only the important information in memory. The new discoveries,…

UT study: Lack of ZZZZs may zap cell growth, brain activity

On October 31, 2015, Posted by , In Buzz, By ,,,,,, , With No Comments

Lack of adequate sleep can do more than just make you tired. It can short-circuit your system and interfere with a fundamental cellular process that drives physical growth, physiological adaptation and even brain activity, according to a new study from the University of Tennessee, Knoxville. Albrecht von Arnim, a…

Everyone has their own daily rhythm of digital activity, shows study

On October 8, 2015, Posted by , In Buzz, By ,,,,,,, , With No Comments

Over the past decade, there has been a surge of scientific studies on the digital activity of people, such as making mobile calls, texting, e-mailing, and posting on social media. Because nearly all human behavior leaves a digital footprint, scientists can use such digital activity as a proxy to track…
