近年来,人们发现了健康脑连接体的各种重要的拓扑性质。然而,脑损伤改变功能网络拓扑的方式尚不清楚。我们通过对96例脑损伤患者的脑结构和静息状态功能成像数据进行多元支持向量回归分析,研究了特定脑区在维持网络拓扑结构中的关键作用。患者的皮质病变分布模式可以显著预测功能网络的拓扑结构,预测模型中权重显著的一组区域被识别为“病变中心”。有趣的是,我们发现了两种不同类型的病变中枢,其病变与相对不同方向的网络拓扑变化相关,要么更一体化(全局),要么更分离(局部),并以复杂的方式与健康功能网络中确定的中枢相对应。我们的结果对脑损伤后功能性脑网络的潜在动力学提出了进一步的重要问题。
Various important topological properties of healthy brain connectome have recently been identified. However, the manner in which brain lesion changes the functional network topology is unknown. We examined how critical specific brain areas are in the maintenance of network topology using multivariate support vector regression analysis on brain structural and resting-state functional imaging data in 96 patients with brain damages. Patients’ cortical lesion distribution patterns could significantly predict the functional network topology and a set of regions with significant weights in the prediction models were identified as “lesion hubs”. Intriguingly, we found two different types of lesion hubs, whose lesions associated with changes of network topology towards relatively different directions, being either more integrated (global) or more segregated (local), and correspond to hubs identified in healthy functional network in complex manners. Our results pose further important questions about the potential dynamics of the functional brain network after brain damage.
