CSF pressure is mainly regulated by
Lumbar CSF pressure is normally 70 to 180 mm H2O. Up to pressures well above this range, the rate of CSF formation is independent of intraventricular pressure. However, absorption is propoional to the pressure Ref: Ganong's Review of Medical Physiology Twenty-Third Edition Page No:571
