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 ...

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 ...

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 ...

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 ...

Just as a conductor coordinates different instruments in an orchestra to produce a symphony, breathing coordinates hippocampal brain waves to strengthen memory while we sleep, reports a new ...

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 ...

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 ...

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 ...

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 ...
