Young males are often associated with more violence, leading to some serious negative consequences. However, the physiology and the neuroimaging patterns underlying juvenile violence remain unclear. Of the limited knowledge on juvenile violence, the default mode network has been known to be associated with its pathophysiology. This study aimed to investigate functional connectivity alterations of the default mode network in male juvenile violent offenders. 31 juvenile violent offenders in a high-security facility, who were convicted of aggressive behaviors by court, and 28 normal controls from a middle school were recruited as participants. They underwent a resting-state functional magnetic resonance imaging scan. And independent component analysis approaches were used to analyze their data. Compared to the normal controls, the juvenile violent offenders showed a different default mode network pattern, with the functional connectivity increased in the posterior cingulate, and decreased in the right middle temporal, left angular, right precuneus and right middle frontal cortex. Our findings revealed that the male juvenile violent offenders were associated with abnormal default mode network functional connectivity, which might be a neuroimaging basis for their tendency to violence.

年轻男性往往与更多的暴力有关，导致一些严重的负面后果。然而，青少年暴力背后的生理学和神经影像学模式仍不清楚。在对青少年暴力的有限知识中，已知默认模式网络与其病理生理学有关。本研究旨在调查男性少年暴力犯罪者默认模式网络的功能连接变化。招募了 31 名在一个高度安全的设施中被法庭判定犯有攻击性行为的青少年暴力犯罪者，以及来自一所中学的 28 名正常对照者作为参与者。他们接受了静息状态功能磁共振成像扫描。并使用独立成分分析方法来分析他们的数据。与正常对照相比，少年暴力犯罪者表现出不同的默认模式网络模式，后扣带回功能连接性增加，右颞中叶、左角、右楔前叶和右中额叶皮质功能连接减少。我们的研究结果表明，男性青少年暴力犯罪者与异常的默认模式网络功能连接有关，这可能是他们暴力倾向的神经影像学基础。
