[Mathematical model of intracranial blood-cerebrospinal fluid dynamics system applied to the study of extreme conditions].

A mathematical model of cerebral blood and lymph circulation that can be used to study various effects (simulated space flight factors, functional loads) on the human body was developed. Biophysical patterns that determine relationships between cerebral blood and lymph circulation as well as between fluid volumes and pressures (P and V) are discussed. Involvement of the mechanism of brain circulation autoregulation in cerebral blood and lymph circulation is considered.

[A system of ultrasonic guidance for use in studying the brain (studies on models)].

Ultrasonic echo-impulse devices for brain monitoring, widely used in clinical medicine, permit to achieve a diagnostical information about the location of volume pathological formations in brain and characteristics of intracranial hemodynamics during short-time researches. According to model testing, the developed system of electron search and guidance of ultrasonic rays to intracranial structure elements for monitoring of spinal fluid haemodynamic characteristics in cranial cavity can be used for search, guidance and retention of the chosen direction of ultrasonic sounding for the period of physiological information reading.
