Figure 1. Group Average Brain Activations Associated with Post-Congruent Conflict.

Figure 1

(a) Group differences in brain activations associated with the processing and resolution of cognitive conflict preceded by congruent trials (post-congruent conflict, cI-cC) were detected in fronto-striatal (red) and default mode network (blue) regions. Group average brain activations are shown for the OCD (b) and healthy (c) participants. Increases in signal during correct responses to cI relative to cC trials are shown in red, and decreases are shown in blue. For display purposes, these maps (generated with MRIcroN) are thresholded at P = 0.025, uncorrected, with a cluster filter of 25. The within-group effects did not survive our a priori significance threshold (P = 0.005, cluster filter of 61). The between-group effects remained after controlling for age of onset in the OCD group.
