1. Activation maps of imagery during AS condition show learning effects in experiment 2 (Exp. 2).
Activation maps of imagery during AS condition show learning effects in experiment 2 (Exp. 2). A, Significant activation associated with anticipatory imagery (AS > NS). Areas include CB, GP/Pu, thalamus, PCC, presupplementary motor area (pre-SMA), and SMA proper. B, Sagittal view of medial frontal activation. Dotted line indicating Talairach coordinate axis, y = 0, separates pre-SMA and SMA proper. C, ROI analysis reveals percentage signal change differences in the AS conditions compared between run 1 (shaded) and run 2 (white) (*p < 0.05). ROIs were defined by analysis shown in A. Error bars indicate SEM.
