精神病是一种与犯罪行为密切相关的人格障碍。使用[18F]fallypride PET和BOLD fMRI,我们发现冲动-反社会精神病特质选择性地预测了多巴胺释放和奖励预期相关的神经活动,分别响应于药理学和货币刺激。这些研究结果表明,多巴胺能奖励系统的神经化学和神经生理高反应性可能包括冲动,反社会行为和精神病药物滥用的神经基板。
Psychopathy is a personality disorder that is strongly linked to criminal behavior. Using [18F]fallypride PET and BOLD fMRI, we show that impulsive-antisocial psychopathic traits selectively predict nucleus accumbens dopamine release and reward anticipation-related neural activity in response to pharmacological and monetary reinforcers, respectively. These findings suggest that neurochemical and neurophysiological hyperreactivity of the dopaminergic reward system may comprise a neural substrate for impulsivity, antisocial behavior and substance abuse in psychopathy.
