(A) Regions where inhibition-related activation is negatively correlated with ADHD symptom severity. See Table 2 for detailed cluster information. The statistical map is corrected for whole-brain multiple comparisons and projected onto an average cortical surface using CARET (R = Right). The color bar represents the z-score. (B) Regions of overlap between pre-defined regions of interest and Fig. 2A; i.e. regions identified in neurotypicals as inhibition-related that also demonstrate correlation with symptom severity in adults with ADHD. (C) Scatter plots visualizing the correlation in these regions among ADHD participants: inhibition-related activation as a function of ADHD symptom severity. Inhibition-related activation quantified as difference in % signal change between rare- and prevalent-No-go, averaged across voxels in the clusters presented in B.
