title: [Dynamics of the cerebrospinal fluid and elastic properties of the cerebrospinal system (a bolus technic)].
abstract: The theoretical aspects of employing the infusion methods of examination of CSF time course and viscoresilient properties of the cerebrospinal system (CSS) are discussed. The general formula of changes in the time of intracranial pressure (TIP) after a load is given. Dog experiments showed this formula to reflect sufficiently exactly the behavior of the CSS in a TIP range of 24 to 40 cm H2O. Analysis of the data in the literature and the results of the author's studies allows the conclusion that determination of CSF resorption resistance by the method of infusion under constant pressure with subsequent calculation of the CSS resilience gradient from the curve of TIP reduction makes it possible to avoid the disadvantages of the bolus technique.
