对于引导愤怒、愤怒沉思以及攻击性人格的神经回路，我们知之甚少。在当前的功能性磁共振成像实验中，参与者受到侮辱并被诱导进行沉思。背侧前扣带皮层的活动与自我报告的愤怒感受以及一般攻击性的个体差异呈正相关。内侧前额叶皮层的活动与自我报告的沉思以及置换性攻击的个体差异有关。在受到挑衅后，海马体、脑岛和扣带皮层的激活增加预示着随后自我报告的沉思。这些发现通过明确介导愤怒和愤怒沉思的主观体验的神经区域以及与不同类型攻击行为相关的神经通路，增进了我们对与攻击行为风险相关的神经过程的理解。
Very little is known about the neural circuitry guiding anger, angry rumination, and aggressive personality. In the present fMRI experiment, participants were insulted and induced to ruminate. Activity in the dorsal anterior cingulate cortex was positively related to self-reported feelings of anger and individual differences in general aggression. Activity in the medial prefrontal cortex was related to self-reported rumination and individual differences in displaced aggression. Increased activation in the hippocampus, insula, and cingulate cortex following the provocation predicted subsequent self-reported rumination. These findings increase our understanding of the neural processes associated with the risk for aggressive behavior by specifying neural regions that mediate the subjective experience of anger and angry rumination as well as the neural pathways linked to different types of aggressive behavior.
