During the course of preparations for space flight and during its execution the crews of the Soyuz-3-9 exhibited similar disturbances in the rhythms of sleep and wakefulness associated, on the one hand, with the influence of modified daily schedules and on the other hand, neuropsychic stress and weighlessness. The dynamics of higher nervous activity of these cosmonauts during space flight revealed four stages: (1)deterioration in the general feeling of well being, performance and sleep, (2) recovery and retention of functional state and performance of the cosmonauts to a high level, (3) gradual decline in functional state and performance of the cosmonauts, and (4) brief increase in functional state and performance of the cosmonauts immediately before landing. During the postflight period there was a general slowing in the rate of resynchronization of the sleep and wakefulness rhythms. (Author)
