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 ...

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 ...

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

This discovery, resulting from research conducted at the University of Copenhagen, sheds light on a key process: slow brain waves, orchestrated by norepinephrine, act as a pump to eliminate ...

Danish scientists found that a molecule called norepinephrine plays a key role in the brain's cleaning in mice. During deep sleep, the brainstem releases tiny waves of norepinephrine about once ...

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 ...

Delta waves (0.5-4 Hz) signify a state of deep sleep. A binaural beat with a frequency between 4 and 7 Hz, for example, is more likely to align with theta brain waves, promoting sleep and relaxation.

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 ...

Danish scientists found that a molecule called norepinephrine plays a key role in the brain’s cleaning in mice. During deep sleep, the brainstem releases tiny waves of norepinephrine about once ...

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% ...

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 ...
