Activation (mean percent of voxels with z-scores > 3) in right brain regions a 1-back task. b 2-back task. c 1-back task versus 2-back task for three regions with greatest levels of activation: right middle frontal gyrus, DLPFC, and posterior parietal lobe. Key: Brain regions with valid fMRI data: precentral gyrus (orange), anterior cingulate gyrus (blue), anterior parietal lobe (yellow), inferior frontal gyrus (green), posterior parietal lobe (red), dorsolateral prefrontal cortex (purple), middle frontal gyrus (black)
