The brain's cerebrospinal fluid (CSF) pulses during deep sleep and this appears to be tied to brain wave activity and blood flow, an exploratory study showed. Large oscillations of CSF inflow to the ...

Research headed by teams at the University of Rochester Center for Translational Medicine and the University of Copenhagen describes for the first time how a spreading wave of disruption and the flow ...

New research from Boston University suggests that tonight while you sleep, something amazing will happen within your brain. Your neurons will go quiet. A few seconds later, blood will flow out of your ...

A popular hypothesis for how the brain clears molecular waste, which may help explain why sleep feels refreshing, is a subject of debate. Encased in the skull, perched atop the spine, the brain has a ...

Sleep is profoundly restorative for the brain, partly because it clears solutes and waste products. This flushing works best during the deepest periods of sleep, but why is that? Data from the lab of ...

We think of our brains as many things: the seat of the mind, the place where our memories live, or perhaps the world’s most powerful supercomputer, but you might be surprised to learn that our brains ...

Why sleep has restorative—or damaging—effects on cognition and brain health has been an enduring mystery in biology. Researchers think cerebrospinal fluid (CSF) may flush toxic waste out, “cleaning” ...

Scientists at the Institute for Basic Science (IBS) have uncovered a non-invasive method to boost the brain’s natural waste drainage system—a discovery that they suggest could open new avenues for ...
