Hysteresis in the relationship between cerebrospinal fluid absorption minus formation and cerebrospinal fluid pressure in the dog.

Abstract

In this study the difference between cerebrospinal fluid (CSF) absorption and formation (A -- F) was measured as a function of CSF pressure in the living and dead dog. We determined this relationship between A -- F and CSF pressure during both increasing and decreasing CSF pressures. A hysteresis effect was identified in 78% of living animals, but was not seen in the dead animals. This suggests that the mechanism of CSF absorption in the living dog is nonpassive and pressure-sensitive.
