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

While physical activity is known to slow cognitive decline in Alzheimer’s disease, many patients are unable to exercise due ...

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

The effect was especially strong during non-REM sleep — the deep stage critical for memory and cognitive recovery. Researchers also observed changes in brain wave patterns.

The study revealed that even non-REM sleep, the deepest and most restorative stage, became more active under caffeine’s influence. Instead of slowing down, the brain continued processing as if ...

Coffee can help you stay awake. But what does caffeine actually do to your brain once you're asleep? Using AI, a team of researchers has an answer: it affects the brain's "criticality ...

Sleep Cycles: One rapid eye movement (REM) stage and three non-REM stages that altogether last about 90 to 120 minutes Benefits: Physical and mental recuperation and memory consolidation Disorders ...

Brain activity patterns during sleep (NREM and REM), comparing caffeine versus placebo effects on periodic neural oscillations (after removing aperiodic spectral components).

Caffeine shifts brain activity during sleep by increasing EEG complexity and reducing long-range temporal correlations, particularly in non-REM (NREM) sleep. These changes reflect a movement ...

The study, published in the Journal of Neuroscience, maps the brain’s electrical activity during lucid dreaming, offering unprecedented insights into this mysterious state of consciousness.The ...

What is REM sleep? "REM sleep is the final stage of the sleep cycle where the brain becomes highly active, almost as if it’s awake, while the body remains relaxed. This is the stage where vivid ...

Meta plans to address these limitations in future research by improving the accuracy and reliability of the decoding process, exploring alternative non-invasive brain imaging techniques that are ...
