Table 2 shows the between group differences in brain activation. The statistical significance threshold for examining this effect was set at p=0.01 and a cluster size of 219 voxels corresponded to a corrected p=0.05. Clusters of significant activity are represented with voxel of peak activation, peak Z-score, and MNI coordinates. MNI, Montreal Neurological Institute; L, left; R, right; sup, superior; inf, inferior; ant, anterior. LetterNogo>LetterGo (Letter No-go – Letter Go); HappyNogo>HappyGo (Happy No-go – Happy Go); SadNogo>SadGo (Sad No-go – Sad go); Group X Sad Emotion X Go/No-go Interaction (Interaction between group, sad stimuli, and response type). The statistical significance threshold for examining this effect was set at p=0.01 and a cluster size of 219 voxels corresponded to corrected p =0.05, except for the interaction between groups (10DAT & 9DAT) and condition (sad no-go>sad go, letter no-go > letter go) the statistical significance threshold for examining this effect was set at p=0.05 and a cluster size of 935 voxels corresponded to corrected p=0.05.
