For decades, scientists have mapped attention, memory, language, and reasoning to separate brain networks — yet one big mystery remained: why does the mind feel like a single, unified system?

Aging compromises the lymphatic vessels (green) in tissue called the meninges (blue) surrounding the brain, disabling waste drainage from the brain and impacting cognitive function. Researchers at ...

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 ...

It’s been known for millennia that the human body accumulates waste as a result of day-to-day functioning, but it’s now recognized that the awake, active brain also builds up waste that negatively ...

Scientists have restored the brain's waste-clearing process in aging mice, offering potential new treatment for Alzheimer's and Parkinson's using existing drugs. Alzheimer's, Parkinson's, and other ...

Our bodies rely on their lymphatic system to drain excessive fluids and remove waste from tissues, feeding those back into the blood stream. It’s a complex yet efficient cleaning mechanism that works ...

As aging bodies decline, the brain loses the ability to cleanse itself of waste, a scenario that scientists think could be contributing to neurodegenerative conditions such as Alzheimer's disease and ...
