Cortical activity associated with relevant and irrelevant reward. A, The actual prospect of reward, defined by comparing relevant potential-reward with no-reward trials, engaged various prefrontal regions, including right dlPFC and inferior frontal junction, right IFG, and lateral frontopolar cortex (lf polar), as well as bilateral FG and inferior parietal cortex (IPC). B, Irrelevant reward information, defined by comparing incongruent reward-related with incongruent reward-unrelated words in no-reward trials, was associated with increased activity in dlPFC and FG, as well as in the right middle temporal gyrus (MTG). C, Neural activity associated with relevant reward (white) and irrelevant reward (black) is overlaid to illustrate the activity overlap (gray) within right dlPFC and bilateral FG (display cutoff p < 0.001).
