fMRI activation maps for ARND subjects with and without diagnoses of ADHD. (A) Disjunction contrast (FWE p = 0.001, corrected for multiple comparisons using cluster size = 10). (B) Conjunction contrast (FWE p = 0.001, corrected, cluster size = 10). (C) Conjunction minus disjunction contrast (FWE p = 0.05, corrected, cluster size = 22). R, right; L, left. The color of the activations corresponds to increased significance with increasingly hot colors (black-red-yellow-white); activations range from T = 1.9 (p = 0.05) for (C) and T = 3.9 (p = 0.001) for (A) and (B) to a maximum of T = 14.
