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 ...

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 ...

The space between the arachnoid and pia meningeal layers encasing the brain is a landscape of connective tissue, blood vessels, and cerebrospinal fluid. Scientists debate how that fluid moves within ...

If you find it hard to focus after a wakeful night, it’s because your brain is busy trying to catch up on crucial ...

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 ...

The choice of 810 nm is also supported by photobiology: this wavelength aligns well with the absorption spectrum of cytochrome c oxidase (the mitochondrial “light receptor”) and has been widely used ...

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 ...

A device that massages the face and neck boosts the brain’s waste disposal system, suggesting it could reduce the severity of conditions like Alzheimer’s disease. Cerebrospinal fluid (CSF) bathes our ...

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 ...

Nearly everyone has experienced it: After a night of poor sleep, you don't feel as alert as you should. Your brain might seem foggy, and your mind drifts off when you should be paying attention.
