Region of interest (ROI) activation. (A) Cluster of significant correlation between right amygdala activation (peak voxel at 30, −2, −18) of the contrast unpleasant relative to neutral pictures and subjective arousal overlaid on a single subject T1 scan (overlay threshold: p < 0.05; minimum cluster size of k = 5). Color-coded t-values are shown. (B) Correlation between right amygdala activation (peak voxel at 30, −2, −18) of the contrast unpleasant relative to neutral pictures and subjective arousal.
