[Training of rats of the Wistar and Krushinskii-Molodkinaia lines in a radial maze].

The experiments were conducted on rats of Wistar (W) and Krushinsky--Molodkina (KM) (with audiogenic epilepsy) lines in 12-rays radial-symmetrical labyrinth. The trained rats of W line made less erroneous (repeated) visits to the labyrinth corridors than the rats of KM line. The corridors repeatedly visited by the rats of W line were more frequently situated near the unvisited corridors. No definite sequence of corridors' visiting by the rats of both lines was observed; still there was a tendency to choose corridors the most remoted from each other. This tendency intensified in the process of training. This is considered as one of tactics of rats' behaviour, providing for adequate reactions in definite surrounding conditions.
