[Reproduction of a conditioned defense reflex in mice in a water maze].

The characteristics of formation of the reflex of water avoidance in a water maze and the dynamics of its reproduction during 24 hours after its elaboration were studied in mice. In case of incomplete initial learning the reflex reproduction had a phasic, oscillating nature. It is assumed that this oscillating dynamics is due to corresponding changes in the similarity of biopotentials in the cortical areas which participate in the formation of the conditioned connection.
