Previously Unknown Cleaning System in Brain Discovered

University of Rochester neuroscientists found a fast, pressurised system that flushes cerebrospinal fluid through the brain along channels around blood vessels, clearing away waste much as the lymphatic system does elsewhere in the body. They named it the glymphatic system. It was seen in mice using live two-photon imaging, and the team suggests it may matter for brain injury, Alzheimer's, stroke and Parkinson's.
