In the last decades, science has taught us that the mammalian brain isn’t always entirely awake or asleep. Dolphins can swim with one hemisphere asleep while the other is alert, and some neurons in ...

People with breathing problems during sleep may have a larger hippocampus, the area of the brain responsible for memory and thinking, according to a study published in the December 18, 2024 ...

As we sleep, rhythmic waves flush cerebrospinal fluid deep into the brain. Once there, the fluid mops up debris and waste before being flushed out again, taking all of the gunk with it.

If your anxious brain is keeping you up at night, Eti Ben Simon has some not-so-great-news: The sleep you lose to stress might exact an additional emotional toll on your wellbeing the next day.

Poor sleep quality is associated with accelerated brain aging, according to a recent study. People with more sleep issues had brain ages up to 2.6 years older than those with fewer issues.

After the screening, 113 volunteers were included in the study and randomly assigned to one of three investigation cohorts – the late-night sleep deprivation group (n = 41; sleep duration from ...

During a pre-deep sleep stage, dubbed N2 sleep, certain spikes in brain activity can be detected. These spikes are called sleep spindles, and they have been associated with memory retention.
