    the brain cleanse itself? Now, the main way to remove brain toxins is known. The findings could help understand how age-related diseases such as Alzheimer's developed. The results have been published in Nature.
    Gou Young Koh of the Korea Institute of Advanced Science and Technology, says the location of cerebrospinal fluid entering and leaving the brain has always been a mystery. In 2014, scientists discovered a network of blood vessels called meninges lymphatic tubes on the outer membrane of the brain. It plays a role in regulating fluids in the brain and removes excess proteins that accumulate in the brain.
    , however, because of the complex structure of the brain, it is not clear where most of the fluid is coming in and out.
    to determine the flow of fluid, Koh and colleagues injected dyes and tracer into the mice's cerebrospinal fluid and then used brain scans to track where they flowed out of the brain. The study found that the substrate meninges lymphatic tube allows cerebrospinal fluid to flow in and out of the brain at the base of the skull, not at the top.
    team also found a significant reduction in cerebrospinal fluid draination in older mice. Mice 2 years of age or older were about half as likely to pass through the substrate lymphatic tube as mice 3 months old.
    "It's such a fundamental anatomical problem that we don't know how something as important as the fluid around the brain is removed." It's amazing. "However, the discussion is not over yet, " says Steven Proulx of the University of Bern in Switzerland. Our finding is that the path of circulation in the nasal area and even in the visual region is just as important, or even more important. The
    cerebrospinal fluid is considered important for brain health. For diseases like Alzheimer's, proteins such as amyloid build up in the brain and can cause damage.
    proulx says there may be several ways the brain drains fluid, including the spine. "Understanding where this flow occurs is important to understanding the immune response that can occur through the central nervous system and how to remove toxic proteins such as amyloid." (
