The nature of cerebrospinal fluid formation

Background and purpose: The aim of the study was to determine if a change in intracranial pressure affects the cerebrospinal fluid formation measured by ventriculocisternal perfusion technique in the whole cerebrospinal fluid system. Material and methods: Domestic cats of both sexes were used. Ventriculocisternal perfusions were perfomed and the rate of cerebrospinal fluid formation was calculated by equation of Heisey et al. Results and conclusions: It was shown that the rise in intracranial pressure significantly decreased the rate of cerebrospinal fluid formation. Since the formation of cerebrospinal fluid should be independent of the intracranial pressure, the obtained findings indicate that the nature of formation is a passive rather than an active process.
