A study found that poor sleep can negatively impact how well the brain flushes out toxins, increasing the risk of dementia.

New research shows that during moments of lost focus after poor sleep, the brain releases a wave of cerebrospinal fluid (CSF)—the same cleansing process that normally occurs during deep sleep.

Neuroscientists probing the boundary between sleep and awareness are finding many types of liminal states, which help explain ...

An international consortium of researchers has created the largest-ever database compiling records of brain activity during ...

You can see it coming in right there, that little spot,” says neuroscientist and engineer Laura Lewis. A remarkably bright pulsing dot has appeared on the monitor in front of us. We are watching, in ...

In the new study, researchers demonstrated that the human brain falls asleep abruptly, rather than gradually, with a "tipping point" marking the transition from wakefulness into sleep. They were then ...

Deep sleep mobilizes a peculiar interaction between neural waves and brain fluid, that is crucial for memory consolidation ...

The brain has its own waste disposal system—known as the glymphatic system—that's thought to be more active when we sleep. Subscribe to our newsletter for the latest sci-tech news updates. But ...

Scientists have assembled the largest collection of dream data ever created, pooling more than 2,600 sleep recordings from ...

During sleep, the brain must achieve a delicate balance: disconnecting from sensory input to allow restorative functions, while remaining alert enough to wake if danger arises. How does it sort ...
