A delay in getting to the rapid eye movement (REM) stage of sleep may be linked to Alzheimer's disease and related dementias, ...

As you lay your head down to sleep tonight and dream all things weird and wonderful, scientists think your brain is going ...

Now, a Danish study led by postdoc researcher Natalie Hauglund from the University of Copenhagen and the University of Oxford ...

This important study assessed the effects of food intake on sharp wave-ripples in the hippocampus of mice during subsequent sleep. Solid evidence supports the conclusion that sharp wave-ripples are ...

Introduction During the first wave of the COVID-19 outbreak in China, the surge of COVID-19 cases was rapid and drastic. Emerging evidence suggests that beyond the acute phase, patients with COVID-19 ...

slow brain waves, orchestrated by norepinephrine, act as a pump to eliminate accumulated waste. This mechanism, mainly active during deep sleep, could explain why poor sleep increases the risk of ...

The body and mind need rest to function properly, and the brain is no exception. During sleep, a crucial process known as the glymphatic system works to clear waste products from the brain ...

which was released by the brainstem every 50 seconds during the non-rapid eye movement sleep. The wave of norepinephrine generates oscillating blood volume, pushing the fluid around the brain to ...

But a smarter generation of “sleep buds” is set to arrive, and the products embrace new tricks — from tracking your motion to measuring your brain waves — to make sure you conk out.

Scientists discovered that norepinephrine, released in rhythmic waves during deep sleep, drives the brain’s glymphatic system, which pumps cerebrospinal fluid to clear toxins. However, sleep aids like ...

For the first time a new study describes the synchronized oscillations during sleep that power the brain’s glymphatic system to help remove ‘waste’ associated with neurodegenerative diseases ...

During sleep, norepinephrine triggers rhythmic constriction ... paint the whole picture of the dynamics inside the brain, and these slow waves, micro-arousals, and the norepinephrine were the missing ...
