这篇选择性综述从认知神经科学的角度提供了冲动性攻击的神经生物学模型。有人认为，冲动性攻击的典型案例，与愤怒有关，涉及急性威胁反应系统结构的招募，即杏仁核，下丘脑和导水管周围灰质。有人认为，这些结构的招聘是否会导致冲动性攻击或不反映的功能作用的腹内侧额叶皮层和背内侧额叶和前额叶皮层的反应选择。也有人认为，冲动性攻击可能是因为决策受损而发生的。攻击可能不会伴随着愤怒，但它会反映出对行为的回报/利益的评估被打乱。
This selective review provides a model of the neurobiology of impulsive aggression from a cognitive neuroscience perspective. It is argued that prototypical cases of impulsive aggression, those associated with anger, involve the recruitment of the acute threat response system structures; that is, the amygdala, hypothalamus, and periaqueductal gray. It is argued that whether the recruitment of these structures results in impulsive aggression or not reflects the functional roles of ventromedial frontal cortex and dorsomedial frontal and anterior insula cortex in response selection. It is also argued that impulsive aggression may occur because of impaired decision making. The aggression may not be accompanied by anger, but it will reflect disrupted evaluation of the rewards/benefits of the action.
