Brake failure: reduced size of frontal cortex in Antisocial Personality Disorder

• A pattern of disregard for, and violation of, the rights of others (DSM-IV-TR, 2008)

• Also referred to as ‘psychopathy’ and ‘sociopathy’

• Left hemisphere of the brain• Comparing violent/ non-violent

individuals• Left image is outter (lateral) left-

hemisphere; right image is inner (medial) left-hemisphere in reverse

• Left-medial-prefrontal cortex is outlined: shows reduced volume in violent individuals

• These are signs that something different is going on in the brains of pathologically aggressive people

(Narayan et al., 2007)
