One key role of sleep involves cerebrospinal fluid, which surrounds and protects the brain. During sleep, CSF helps remove ...

A new study from Karolinska Institutet, published in Nature Communications, reveals how rhythmic brain waves known as alpha oscillations help us distinguish between our own body and the external world ...

Gamma brain waves are rhythmic electric processes in nerve cells called neurons. Nerve activity in the brain allows for communication throughout the brain to carry out functions such as memory, ...

At what point do "you" end and the outside world begins? It might feel like a weird question with an obvious answer, but your ...

Understanding the link between brain activity and behavior is among the core interests of neuroscience. Having a better grasp of this relationship will both help scientists understand how the brain ...

These wide-ranging waves quickly link the specific constellations of brain regions that work in harmony to perform a task. In the space of just a few seconds, a person walking down a city block might ...

The timing of our brain waves shapes which words we hear. Researchers used psychophysics, neuroimaging, and computational modeling to test whether neural timing influences perception of more or less ...

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 ...

Sleep and wake: they’re totally distinct states of being that define the boundaries of our daily lives. For years, scientists have measured the difference between these instinctual brain processes by ...

As if we didn’t have enough reasons to get at least eight hours of sleep, there is now one more. Neurons are still active during sleep. We may not realize it, but the brain takes advantage of this ...
