Brain sleep

What is your pre-bedtime routine? Drink a glass of milk, clean your teeth, prepare your bed? Studies have found many animals engage in habitual behaviors before sleep, but until now researchers have not known the neurobiological mechanisms that are activated by these pre-sleep routines.

Sleep is a mystery to many of us, but scientists know quite a bit about how it affects us. Here’s what happens to your body when you fall asleep.

Sound stimulation can manipulate brain waves during REM sleep, a stage crucial for memory and cognition.

While mice sleep, their brain cells shrink, allowing cerebrospinal fluid to flow easily around them. The fluid can then clear away toxins. This finding appears to offer the best explanation yet of why animals and people need sleep.

There’s a Lot of Hard Work Being Done While You Slumber

A new study reveals a potential link between sleep apnea, reduced time in deep sleep, and brain biomarkers associated with increased risk of conditions like stroke, Alzheimer’s disease, and cognitive decline.

While we're sleeping, our brains act as filters to determine whether or not we should wake-up to address a sound. If we don't wake-up, we don't make a memory of having heard the sound. #sleep #evolution #sleepscience

Stimulating the sleeping brain may ease suffering from memory loss, stroke or mental health
