Previously Unknown Cleaning System in Brain: Newer Imaging Technique Brings 'Glymphatic System' to Light

"...It's a hydraulic system," said Nedergaard. "Once you open it, you break the connections, and it cannot be studied. We are lucky enough to have technology now that allows us to study the system intact, to see it in operation."..."Understanding how the brain copes with waste is critical. In every organ, waste clearance is as basic an issue as how nutrients are delivered. In the brain, it's an especially interesting subject, because in essentially all neurodegenerative diseases, including Alzheimer's disease, protein waste accumulates and eventually suffocates and kills the neuronal network of the brain..."

A previously unrecognized system that drains waste from the brain at a rapid clip has been discovered by neuroscientists. The highly organized system acts like a series of pipes that piggyback on the brain's blood vessels, sort of a shadow plumbing system that seems to serve much the same function i...
