基于传递熵对反社会行为大脑效应连接模式的研究

Detecting abnormalities in the brain network associated with antisocial behavior using transfer entropy

  • 摘要: 研究采用传递熵方法对反社会行为(antisocial behavior, ASB)个体的大脑功能异常进行了神经网络效应分析。结果显示,ASB组的效应连接全局同步性显著下降,同时节点的介数中心性和度中心性存在显著差异。其中,右侧颞叶、左侧枕叶及梭状体的节点介数中心性显著降低,而左侧额下回、脑岛和楔前叶则显著增加。节点度中心性的变化表现为右侧额中回等区域降低,而双侧中央后回、左侧颞下回、脑岛等区域升高。此外,ASB组在14个典型大脑网络中呈现显著不同的效应连接模式。这些发现为理解反社会行为的神经基础提供了重要启示。

     

    Abstract: In this study, the transfer entropy method is used to investigate the neural network effects on brain functional abnormalities in individuals with antisocial behavior (ASB). The results reveal a significant decrease in global synchronization properties within the ASB group, and most importantly, significant regional differences in nodal betweenness and nodal degree centrality. Particularly, individuals with ASB exhibit a significant decrease in nodal betweenness centrality in the right temporal lobe, left occipital lobe, and fusiform, coupled with a significant increase in the left inferior frontal gyrus, insula, and precuneus. Alterations in nodal degree centrality manifest a decrease in regions such as the right middle to medial frontal gyrus and superior occipital lobe, alongside an increase in regions such as the bilateral posterior central gyrus, left inferior temporal gyrus, and insula. Furthermore, the ASB group displays significantly different connectivity patterns across 14 typical brain networks. These findings provide important insights for understanding the neural basis of antisocial behavior.
