WebJul 7, 2024 · CSF is formed in the choroid plexus by both filtration and active transport. In normal adults, the CSF volume is 90 to 200 mL [ 1 ]; approximately 20 percent of the CSF is contained in the ventricles; the rest is contained in the subarachnoid space in the cranium and spinal cord. The normal rate of CSF production is approximately 20 mL per hour. WebThe reported values for this volume vary in the literature, ranging from 90μL [66] to 520μL [67], but seem to be consistently in the region 5-20% of the total intracranial volume.
WebThe volume of the CSF ranges from 35 μl in the mouse to over 100 ml in humans, and the rate of production of CSF ranges from 0.32 μl/min in the mouse to 350 μl/min in humans (Table 1).
