Investigation of human cerebral circulation in spaceflight conditions

The effective control of the main physiological systems during spaceflight and investigation of the mechanisms involved is a difficult problem, but the success of manned space missions greatly depends on the solution of these problems. In this respect, the cerebral circulation system is of particular importance for control and research. The large amount of experimental evidence concerning the functional peculiarities of the cerebral circulation system gives us every reason to suggest that this part of the circulatory system could be readily affected by spaceflight dynamic factor-accelerations and weightlessness.
