Handedness-dependent and -independent cerebral asymmetries in the anterior intraparietal sulcus and ventral premotor cortex during grasp planning

► Equivalent effector-specific grip selection behaviors for left- and right-handers ► Equivalent increases in left vPMC regardless of hand dominance ► Increased aIPS and right vPMC activity in the motor-dominant hemisphere ► Hand dominance predicts the cerebral organization of certain motor cognitive functions.
