title: [The blood circulation and oxygen tension in the brain of waking and narcotized rabbits during head-down tilt exposure].
abstract: The hydrogen clearance technique was used in anesthetized and intact rabbits for studying the changes in the local blood flow in the parietal brain cortex. Phasic changes in the blood flow in the parietal, frontal, occipital, temporal lobes of the brain cortex and changes in the volume rate of the blood flow in the basin of the brain venous sinuses, as well as the oxygen saturation in these zones, were studied in anesthetized rabbits by polarographic method during antiorthostatism (45 degrees) for 30 min. The differences in the reaction of the brain vessels to antiorthostatism were particularly obvious within the first minutes.
