Note. BA10 (anterior prefrontal/orbitofrontal cortex), BA11 (orbitofrontal cortex), BA24 (ventral posterior cingulate cortex), BA25 (subgenual cortex), and BA32 (dorsal anterior cingulate cortex). Difference = Reward – Non-reward. (Frontal source condition effects tested at

^*p < .01; Regional differences tested at

^**p < .005, Bonferroni corrected.)
