[Sexual differences in certain forms of motor asymmetry in rats].
Using three tests, studies have been made on locomotor lateralization in Wistar rats. It was shown that rat prefer the left paw for obtaining food from a tube, this preference being more pronounced in females. Females are more asymmetric also in preference of a side turn in a labyrinth: they choose the right side. In males, the preference of the right and left turns, as well as the absence of locomotor asymmetry were almost equal. These data are rather similar to those obtained for human subjects. Studies on the direction of rotation of rats after apomorphine injections did not reveal any sex differences or populational preferences.
