A study from the University of Pennsylvania used MRI scans to analyze the brains of men with high psychopathy scores. Significant findings showed shrunken regions in the basal ganglia, thalamus, and cerebellum. Most notably, impairments were found in the orbitofrontal cortex and insular regions responsible for emotional regulation and social behavior. Weaker connections were also noted between brain areas linked to empathy and moral reasoning. These findings suggest that psychopaths' behaviors may be biologically rooted, providing insights for identification and potential treatment of antisocial behavior.
Researchers discovered marked structural differences in the brains of psychopaths, notably in areas that control emotional regulation, impulse control, and social behavior.
Psychopaths exhibit shrunken areas in brain regions tied to movement, sensory processing, and emotional regulation, leading to impairments in empathy and moral reasoning.
