Introduction. The hermetically sealed skull has long been considered an important factor for the normal mechanical functioning of the circulatory–metabolic supply that ensures brain activity. Most often neurosurgical interventions are accompanied by cranial trepanation otherwise known as craniotomy. However, up to the present no reliable informative indexes have been presented that clarify the necessity for prompt closing of the skull defect or of retaining it after the operation. Moreover archeological findings indicate that skull trepanation perhaps had “special” treatment purposes. Therefore, the present investigation aimed to reveal the peculiarities of the functioning of the intracranial vascular and CSF systems after neurosurgical craniotomy with evaluation of its positive and negative features. Methods. For investigation of CBF and CSF dynamics two methods were applied simultaneously: 1). transcranial dopplerography (TCDG) of the base segment of middle cerebral artery (MCA) and 2). rheoencephalography (REG) with ipsilateral fronto-mastoidal electrodes position. This provides information from the MCA vascular basin of the hemisphere selected. Recordings from the MultiDop-P and REG 4-02 instruments were transferred through PowerLab-4 interface to Macintosh G-4, OS-10.4.2. Pattern and phase analyses of the simultaneous TCDG and REG changes during the cardiac cycle revealed peculiarities of the intracranial “volume–pressure” (ΔV–ΔP) relation. Fifteen
