FIG. 1.

Group comparison (t test) maps, thresholded as described in the methods section, during the procedural learning (left, Z = 52) and spatial working memory (right, Z = 34) tasks, overlaid on the overall group average anatomical image. On the procedural learning task, healthy controls displayed greater activation in the frontal eye fields (FEF), middle frontal gyrus (MFG), motor and posterior cingulate cortices (CING), and in the intraparietal sulcal (IPS) region. On the spatial working memory task, greater activation among the EI subjects was seen in the FEF, MFG, IPS, and precuneus (PREC) region.
