[Semicircular canal function following a flight aboard biosatellite "Cosmos-936"].

The nystagmic reflex, latent period, total and mean number of events, and their duration were measured in the rats flown for 18.5 days aboard the biosatellite Cosmos-936 under the conditions of weightlessness and artificial gravity. The studies demonstrated that prolonged weightlessness did not influence the receptor formations and centers of semi-circular canals. A long exposure to artificial gravity brought about a decrease in reactivity and sensitivity of semi-circular canals. The mechanisms of these phenomena are discussed.
