概括

精神分裂症 (SCZ) 的攻击性行为涉及不同的神经模式. 精神分裂症患者在竞争任务中表现出与事件相关的潜在变化 (ERP),

科学领域:

神经科学
精神病学
认知科学

背景情况:

精神分裂症 (SCZ) 的神经攻击机制尚不清楚.
没有先前的研究使用竞争反应时间任务 (CRTT) 检查了SCZ中的事件相关潜在 (ERP) 特性.
研究SCZ中的ERP攻击相关性对于理解潜在的神经过程至关重要.

研究的目的:

探索精神分裂症中攻击性行为的神经机制.
与健康对照组相比,确定与SCZ患者的攻击相关的特定事件相关潜力 (ERP) 差异.

主要方法:

招募了40名SCZ患者和42名HC患者.
通过验证的问卷 (反应性积极性问卷,巴拉特冲动性量表11,PANSS) 评估攻击性,冲动性和精神病理.
在CRTT期间测量的ERP (P2,N2,P3,FRN).

主要成果:

这样一来,
在决策过程中,SCZ患者表现出更高的N2和P2幅度.
在结果评估期间,SCZ患者的FRN和P3幅度较低.
与阳性症状严重程度相关的N2幅度 (PANSS- P);与一般症状严重程度相关的P3幅度 (PANSS- G).

结论:

精神分裂症患者在CRTT期间表现出异常的ERP模式.
这些ERP变化表明SCZ中具有明显的神经相关性.

Aggression

Aggression

Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...
