N2 and P3 are peak amplitudes in microvolts averaged across 8 recorded scalp sites (EGI sites 4,5,6,11,12,13,20,113).

IFG and rACC are average current density in the N2 time window in the identified inferior frontal gyrus and rostral anterior cingulate clusters, respectively.

Accuracy is proportion accurate (number correct / total trials).

Reaction time is milliseconds from stimulus onset.

^*All significant comparisons are described in the Results text.
