Every minute or so during non-rapid eye movement (NREM) sleep, the brain releases a wave of norepinephrine, a hormone that is one of the brain’s primary neurotransmitters. Norepinephrine is a ...

and found that the norepinephrine waves during sleep decreased by 50 percent and fluid transport into the brain decreased by around 30 percent in zolpidem-treated mice. These results suggest that ...

Researchers have discovered that positive emotions enhance perceptual memories during sleep, particularly in the non-REM stage.

electrodes are attached to your scalp that will monitor brain waves before, during, and after sleep. The EOM records eye movement. A small electrode is placed 1 centimeter above the outer upper ...

OxStu's breakdown on the science behind sleep, providing practical advice on how to establish a good sleep routine.

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.

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

During a good night’s sleep, the brain gets busy cleaning itself, flushing out waste products that have built up during the day. A study in mice shows how a molecule called noradrenaline ...

These norepinephrine waves occur during NREM ... Otherwise, we risk exacerbating sleep problems, potentially worsening brain health in the process. Receive a weekly dose of discovery in your ...

The team focused on the relationship between norepinephrine and blood flow during deep sleep. They found that norepinephrine waves correlate to variations in brain blood volume — suggesting that ...

disrupting the glymphatic system and impeding the brain’s waste-clearing processes, a finding that may raise concerns about its long-term use. Norepinephrine waves during deep sleep were 50% ...
