. Risk Factors for the Development of Neuro-Psychic Asthenia with an Astronaut during a Lengthy Space Flight // Tomsk State Pedagogical University Bulletin. 2002. Issue 3 (31). P. 9-18

This article is aevoted to the analysis of the problem of neuro-psychic asthenia applied to the conditions of a lengthy spaceflight. Psychogenic and somatogenic prerequisites for the development of the neuro-psychic asthenia under these conditions are being examined. The main attention is given to the analysis of fomatopsychic effects of weightlessness, conditioned by such factors as changes in cerebral hemodynamics, functional deaferentation, electrolyte and endocrine imbalance. Theoretical analysis is verified by results of investigating peculiarities of cerebral circulation and structural features of an astronaut's brain, obtained through the methods of magnetic resonance tomography (MR-scan) and transcranial ultrasonic-Doppler in early postflight period.
