Asymmetry of locomotor activity in rats during of food-searching behavior

In the conditions of free movement in the Y-shaped labyrinth the existence of an individual profile of locomotor activity lateralization in non-linear rats was shown. Observed locomotor asymmetry was initially revealed in different number of right-side and left-side motions in Y-shapedlabyrinth without food bait. Placement of a foodin the not preferred compartment of labyrinth changed motive preferences in 100 % of rats with bilateral profile of locomotion, in 65 % of rats with left profile and only in 33 % of animals with right locomotor profile. The data obtained testify that manifestation of locomotor asymmetry in rats during of feeding behavior is determined by a number of factors, including spatial localization of food and type of functional interhemispheric asymmetry.
