Abstract

This survey presents the material of neuroradiologic methods of investigation brain structures and function which changes during space flight. It's taken to attention from inspection of cerebral blood circulation, reversibility of changes in the volumes of gray and white matter, features of neuroplasticity and the formation of new connectivity properties not previously discovered on Earth. The results of magnetic resonance imaging studies, changes in the balance of body fluids, indicators of the cardiovascular system under orthostatic testing, and features of the formation of blood circulation regulation during sleep, which is an integral component of adaptation to microgravity conditions, are presented.
