A joint study has evaluated the usability of a compact EEG device (BrainStatus) developed by Bittium Biosignals from Oulu ...

There's a phenomenon of human hearing known as binaural beats. It occurs when two pure tones of different frequencies are ...

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

sleep or stage 4 (REM dreaming) sleep. Future studies should look more closely into how EEG activity during awake “eureka” moments relates to EEG readings during sleep, researchers said. How the brain ...

Upon waking, all groups showed an improvement in their performance, but 85.7% of those who achieved the N2 sleep phase had their insight moment. In contrast, 55.5% of those who stayed awake and 63.6% ...

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

A 2023 Sleep Foundation survey found that 94% of US adults consume caffeinated beverages, and 64% drink them daily. Of those, 40% said they didn’t think it affected their sleep. What do you think?

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 ...

Dreamers deep in REM sleep have no sense of control over factors like thoughts, feelings, and behaviors, but those in lucid dreaming states do. Demirel also linked gamma waves with lucid dreaming.

According to my Whoop band, I didn't sleep long that night (7:12 hours) but spent a lot of time in REM and deep sleep (2 hours each). This was a significant improvement as I usually spend much ...
