Abstract:
The study of psychophysiological status' interaction and interrelation with parameters of a neurohumoral regulation is important for perfection of medical and psychological support of high serviceability of the crew-members in conditions of space flight. Long-term bed rest in a head-down tilt (BRHDT, antiorthostatic hypokinesia) is used for simulation of prolonged influence of microgravity on a human body in ground-based conditions. The main objective of the present work was to reveal main links of psychophysiological state with neurohumoral parameters in BRHDT.
