Affective traits of psychopathy are linked to white-matter abnormalities in impulsive male offenders.

Our study offers novel insights into the relationships between the four facets of psychopathy and disrupted structural connectivity, and may provide new leads for further characterization of different subtypes of antisocial populations.
