Significant level was set at P < 0.01. Values above the significance level of P < 0.01 are displayed in bold.

F/N dif = Fear neutral difference gmC = Gray matter concentration (after controlling the effect of age and global gray matter).

BDHI = Buss-Durkee hostility inventory; PIS = Plutchik impulsivity scale; NAS = Novaco anger scale; RP = reactions to provocation LPSP = Levenson Self-reported Psychopathy scale. PCL-R. Psychopathy Checklist
