Glymphatic System

The waste-clearance system of the Central Nervous System, primarily active during Deep Sleep.

The Glymphatic System is the brain's waste-clearance network, analogous to the lymphatic system for the rest of the body. It uses cerebrospinal fluid (CSF) to flush metabolic waste (including beta-amyloid) from brain tissue, primarily during deep sleep.

Key Points

  • CSF flow — periarterial inflow, interstitial exchange, perivenous outflow
  • Sleep-dependent — most active during slow-wave sleep
  • Glymphatic Pathway — the route of CSF through the brain; see the Glymphatic Pathway glossary entry for protocol details
