Four recent articles were examined for their use of resting-state functional magnetic resonance imaging on participants with posttraumatic symptoms. Theory-driven computations were complemented by the novel use of network metrics which revealed reduced global centrality and higher efficiency within the default mode network for participants with posttraumatic symptoms. Data-driven methods from other studies revealed associations between functional networks and PTSD symptoms as well as clusters of functional activation corresponding to different PTSD presentations.

创伤后应激障碍的静息状态功能网络模型

对最近的四篇文章对静息态功能性磁共振成像对有创伤后症状的参与者的使用进行了检查。理论驱动的计算得到了网络指标的新用途的补充，这些指标揭示了具有创伤后症状的参与者在默认模式网络中降低的全局中心性和更高的效率。来自其他研究的数据驱动方法揭示了功能网络与 PTSD 症状以及对应于不同 PTSD 表现的功能激活集群之间的关联。
