[Effect of artificial gravitation during space flight on motor habit retention in white rats].
The recovery of a goal-reaching habit (food reaching) was studied in albino rats in a maze after space exposure on biosatellite "Kosmos-936". Animals which were exposed to artificial gravitation during the flight, restored the habit slightly worse than those not centrifuged. The tendency toward worsening is clearly pronounced, although the small number of animals and small changes (which to a considerable degree was due to relatively simple tasks) seem to produce insignificant differences at this stage of the study. The absence of positive effect of artificial gravitation might be connected with a negative effect of angular speeds during centrifugation.
