How to interpret a CSF - The art and the science

Abstract

Cerebrospinal fluid (CSF) was described by Galen as early as the second century as a vaporous humor produced in the ventricles that provided energy to the rest of the body. Interestingly, such theories, although humorous, have not been universally replaced by scientific rationale (http://www.healtouch.com/csft/csf.html).
