Dolan, 2003; Petrides, Alivisatos and Frey, 2002). Again, there was no difference in the signal in FIXED+MONITOR following correct or incorrect feedback. Comparing the activity in the ACC and OFC in these two monitoring conditions showed an interesting functional coupling between the two regions, with there being a negative correlation between signal levels (Figure 4b). This suggests that the degree to which either the ACC or OFC evaluate the consequences of choices depends on the nature of the decision, whether internally guided and voluntarily selected or as the result of external instruction.
