[Retention and recovery of a goal-achieving habit in rats after a flight on biosatellite "Cosmos-782"].
The retention and recovery of food-procuring skill in the maze was impaired in rats after 19.5-days space flight. The study conducted 2--12 days after landing, revealed an increase in the number of erroneous movements and of refusals to cope with the maze, as well as in the time of reaching the goal. These phenomena cannot be explained only by reduction of alimentary excitability and muscular weakness. It is assumed that the observed changes in the higher nervous activity were due to a weakening of the basic nervous processes which might be caused by a decrease in the sensory impulse activity during weightlessness.
