We actually spend around 25% of our sleep in the REM stage as adults, and researchers describe the beta brain waves that are recorded during this time as “similar to brain waves during ...

A new study reveals how the brain reprocesses and refines memories during sleep, particularly those related to spatial ...

But how do sleep cycles work? To find out, I took part in a polysomnography. This is a gold standard sleep study that helps ...

Sleep reorganizes neural patterns in a way that helps memories take hold and prepares the brain for new information.

But it’s not a coma-like state, as in stage 4. Our brain during REM sleep is fully active, guzzling as much energy as when we’re awake. REM sleep is ruled by the limbic system—a deep-brain ...

What if we could obtain the memory, learning and perception benefits of “power naps” without actually sleeping?

“We found that in the early stages of sleep, rats’ brain activity reflected the memories they had just formed. Over time, this activity gradually transformed, preparing the brain to recall the learned ...

Scientists have long recognized the brain's need for energy, but new research from the University of Kentucky's Sanders-Brown ...

New research suggests that people who take significantly longer to start the dream phase of sleep may be showing an early ...

Researchers from ISTA discovered that sleep helps solidify spatial memories by reorganizing neuronal patterns. During non-REM ...

The findings, published in the Proceedings of the National Academy of Sciences, suggest that tiny energy-sensing channels in ...
