[The participation of the right and left hemispheres in the realization of the maze habit in male mice of the BALB/c strain].
Motor, Searching and alimentary activity of male mice BALB/c as well as spatiomotor asymmetry was studied under conditions of training in symmetrical multi-alternative maze. In the period of realization of the stable optimal habit the right-side spatially motor asymmetry was observed in intact males. In animals with inactivated left or right hemisphere motor and alimentary activity was reduced and the structure of elaborated maze habit was broken. These changes were more expressed in mice with inactivated left hemisphere. Searching activity was augmented during cortical inactivation of the right hemisphere (this was associated with the right-side spatially motor asymmetry) and reduced during inactivation of the left hemisphere (associated with the left-side asymmetry). The left hemisphere was dominant in realization of all main components of elaborated maze habit (including the spatially motor asymmetry) in male mice BALB/c as in female ones.
