Submission + - Scientists Explain How the Brain Cleans Itself (medicaldaily.com) 1

An anonymous reader writes: Every organ in the body has to expel waste somehow. Despite the brain's importance in the body, scientists were previously unclear as to how the brain flushed out its toxins, because it did not have a lymphatic system like other organs, which filters out waste. The previous theory stated the cerebrospinal fluid, in which the brain is encased, expelled junk, as waste floated through tissues and made its way onto the surface – but that seemed wildly inconvenient for the amount of waste that the brain must produce. Now, researchers have discovered a second, faster cleaning system on top of the cerebrospinal fluid, and it may shed some light on what happens during disorders that affect the brain.
