Gray Matter Volume and Impulsivity Results of voxel-wise whole-brain analyses examining the relationship between gray matter volume (controlling for age, gender, and intracranial volume) and BIS-11 total and subscale scores. Blue clusters indicate areas where volume is significantly (k>236; p<0.05 corrected) negatively correlated with score. “Total” = BIS-11 total score; “Motor” = BIS-11 motor impulsivity score; “Non-planning” = BIS-11 non-planning impulsivity score. There were no significant clusters related to BIS-11 attentional impulsivity score.
