WebJul 5, 2024 · The earliest research on these ultra-slow waves suggests ISF works by regulating autonomic nervous system function, the flight, fight or freeze response. More importantly, ISF regulates the activation of brain areas linked in chronic autonomic stress by helping the brain communicate between the autonomic and emotional networks. WebThe glymphatic pathway. Cerebrospinal fluid (CSF) enters the brain along para-arterial routes, whereas ISF is cleared from the brain along paravenous routes. Aquaporin-4 (AQP-4)-dependent astroglial water flux mediates the convective bulk ISF flow and drives the clearance of metabolites and waste products from the brain parenchyma.
