The choroid plexus produces approximately 500 milliliters of CSF daily, but only about 150 milliliters are present within the central nervous system at any given time due to constant absorption and replenishment in the brain. This fluid circulates through the ventricles of the brain, the central...
the most powerful factor favoring fluid filtration, is determined by capillary flow, arteriolar resistance, venous resistance, and pressure. Increased capillary filtration can alter the balance of Starling forces at equilibrium
The topics included cover the circulation of the cerebrospinal fluid (CSF): the bloodbrain barrier, the various CSF and brain ions and their effects, acid base balance in the central nervous system, hydrocephalus, ...
CSF appears to be secreted at a fairly constant rate per unit mass of choroid plexus in different mammalian species (Davson and Segal, 1996). However, in different species the mass and surface area of the choroid plexus becomes relatively smaller as the brain size increases. Also, the volume...

this method on young mice and rats, they showed that cerebrospinal fluid enters the brain through small channels primarily at the base of the brain, a route that has not been seen in adults. In addition, they found that cerebrospinal fluid flows to specific functional areas of the brain. ...
