[Formation and interaction of memory traces of the "results" of action in the situation of choosing the direction of movement in space].

The formation of choice between runs to the left or to the right side in rats was studied in aspect of the problem of interaction between memory traces of the signal of locomotion direction and its "result". First a run to the left was elaborated to a tone; the second run--to the right--was elaborated with alternating presentation of light and tone. The closer to the correct choice the longer was the time of performance of both competing reactions. This fact is considered as a result of interaction between memory traces of "results" in their competition for the common final path. The process of singling out of the model of afferent parameters of the "result" of the run to the right was optimized by a preliminary consolidation of memory trace of light's physical parameters used as a signal of its efficiency. The experience of locomotion to the right acquired in these conditions, proved to be resistent against amnesing effect of electric shock.
