[Behavioral and morphological asymmetry in brain weight selected mice].
Mice selected for large and small brain weight preferred to move rightwards in two cognitive paradigms, food-motivated T-maze performance and extrapolation ability tests. The degree of asymmetry in choices of movement direction varied in selection generations and sometimes was accompanied by asymmetry in the weight of the left and right hippocampi and other forebrain structures and different numbers of right and left neocortical cells.
