Abstract :
The assumption that cerebrospinal fluid (CSF) inflow and outflow is an essential element of an intracranial compartment (IC) model has been recently questioned [M. Bergsneider, Neurosurg. Clin. N. Am., vol. 12, p. 631-8, 2001]. The idea proposed by Bergsneider that the free displacement of the CSF is one of the significant sources of the brain compliance is supported in this paper by computing an overall system compliance with a novel algorithm. The compliance obtained using the proposed method is shown to be in the same order of the magnitude as that obtained using the traditional intrusive infusion test technique.
