New research on ‘slow-wave sleep’ may have implications for others battling insomnia, including people with anxiety and ...

A board-certified sleep medicine specialist reviews the history of wearable sleep trackers and explains how clinicians ...

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

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 ...

Earlier studies done mostly on mice discovered that the brain had a system that flushed its tissues with cerebrospinal fluid, which carried away waste products in a process called glymphatic clearance ...

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

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 ...

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 ...

REM sleep goes even deeper into brain recovery, dreaming and processing memories and emotions. This is the sleep stage in ...

They found that during a phase of sleep when the brain is relatively calm, known as non-REM sleep, the neurotransmitter norepinephrine was released in slow waves. These waves caused what the ...

Dec. 12, 2024 — It has been known for nearly 20 years that slow, synchronous electrical waves in the brain during deep sleep support the formation of memories. Why that is was previously unknown.
