A new study finds that entering N2 sleep—a deep phase of non-rapid eye movement sleep—may help lead to more “eureka” ...

New research reveals how synaptic connections in the cerebral cortex can strengthen during sleep, offering insight into how ...

Deep sleep could forestall the declines in brain health that can eventually lead to Alzheimer's disease, the most common form ...

This release examines emerging trends in nighttime weight management and the growing discussion surrounding blue light disruption, NREM sleep, and non-synthetic solutions. It covers the formulation ...

How do animals bounce back from sleep deprivation? Scientists found a subset of neurons in the mouse thalamus that repay this ...

WHAT HAPPENS IN THE BRAIN DURING SLEEP? What Happens During Each Stage of Sleep Have you ever wondered what actually happens ...

SIK3 has a part in regulating both the need for sleep and the amount of NREM (non-rapid-eye-movement) sleep we get each night. This gene is active in synapses—spaces between neurons where messages are ...

After NREM sleep, you move into the REM stage. After REM sleep, you start another cycle. If you get 8 hours of sleep each night, you usually go through four or five cycles.

Sleeping deeply into the afternoon after an all-nighter or a late night out is one way the body repays its sleep debt. The ...

Non-rapid eye movement (NREM) sleep arousal disorders involve repeated episodes of incomplete awakening from sleep, most commonly sleepwalking or night terrors (also known as sleep terrors), but ...

The study itself focuses on NREM sleep, the lighter sleep stage often experienced during naps. Researchers examined neural activity in macaques performing visual tasks before and after a 30-minute ...

NREM 2 sleep is deeper than N1, and we spend a lot more time (up to 50% of our sleep time) in this stage. Our brain activity changes during this time and we see sleep spindles and K-complexes.
