Neuroimaging study reveals those with psychopathy have a 10% larger striatum than non-psychopaths. Researchers say the increased size of the striatum, a brain area associated with cognitive and social functions, may account for a higher likelihood of impulsive behaviors and increased need for stimulation often associated with psychopathy. Additionally, researchers suggest there may be an element of heredity in the neural anatomy, adding support to the neurodevelopmental perspective of psychopathy.
