ABSTRACT

This study was designed to test the hypothesis that degree of neural asymmetry should relate to proficiency at distinguishing left and right. Volume asymmetry was examined in five subcortical structures and compared to performance on two left/right learning tasks. Although anatomical asymmetry was related to the turning bias shown during acquisition, the predicted relationship was not obtained for proficiency scores.
