Although correct rejection contrasts are not of central interest, the lack of PFC activation for sequences involving correct rejections further illustrates the selectivity of the right BA 10 activation during incongruent hits. Activations listed below reach the same threshold as those in Table 1 and the figures (p < 0.0001 with a cluster volume threshold of 20 voxels). Temporal gyrus and thalamic activations may reflect enhanced attention to or anticipation of the auditory cue. There were no significant activations for the incongruent correct rejection > consecutive correct rejection contrasts (which would be more conceptually parallel to the critical contrast for hits) at this threshold. At a more liberal threshold (p < 0.05), the incongruent correct rejection > consecutive correct rejection contrast revealed activations in left inferior frontal gyrus (MNI coordinates: −60, 18, 6) and right superior frontal gyrus (MNI coordinates: 18, 56, 34).
