[Behavior of rats in the labyrinth after a flight on the Cosmos-690 biosatellite]

Rats irradiated aboard the biosatellite Cosmos-690 and in the synchronous mockup showed deteriorated retention and recovery of the skill of traversing the maze. The rats irradiated on the Earth displayed greater changes in the parameters. The rats irradiated inflight exhibited an increased fatigue during enhanced activity. All the exposed animals showed an insignificant change in the capacity to transfer their experience.
