Activation results for the prefrontal regions of interest obtained from the factorial model.

<p>ROIs are shown overlaid on a single subject template included in SPM5 (left). The graphs on the right side show the mean activation profiles depicted for 6 ROIs in the rostral cingulate zone (RCZ, center of mass: x = 4 y = 37 z = 20), pre-supplementary motor area (pre-SMA, center of mass: x = 6 y = 20 z = 58), inferior frontal cortex (IFC, center of mass, left: x = −42 y = 21 z = −11; right x = 46 y = 23 z = 4) and anterior insulae (center of mass left: x = −35 y = 16 z = −10, right: x = 38 y = 18 z = −10). Bars represent mean activity averaged over the depicted respective ROI. Error bars depict the standard error of the mean. Black bars: correct performance, white bars: incorrect performance. *p<.008 (correction for 6 ROIs).
