ROI results.

<p>Percentage signal change in the right OFC (A), the right DLPFC (B), the lingual gyrus (C) and the precuneus (D), is plotted as a function of learning stage (1E vs. 2–5C), learning condition (reward vs. punishment) and reversal (learning vs. reversal). Error bars indicated with-subject standard error. 1E: first error; 2–5C: correct trials during repetitions 2 to 5.
