‘Lymphatic plexus’ behind the nose drains cerebrospinal fluid from the brain, potentially impacting neurodegenerative conditions – In a groundbreaking study published in Nature, South Korean researchers led by Director KOH Gou Young of the Center for Vascular Research within the Institute for Basic Science (IBS) have uncovered a distinctive network of lymphatic vessels at the...
IntroductionCerebrospinal fluid (CSF) is a clear, plasma-like fluid (an ultrafiltrate of plasma) that bathes the central nervous system (CNS). It occupies the central spinal canal, the ventricular system, and the subarachnoid space. Image 1 shows a 3D image of the CSF circulation as it would look inside the skull. CSF performs vital functions including: Support;...
