Multiple neuroimaging studies indicate that posttraumatic stress disorder (PTSD) recovery and symptom reduction are correlated with dynamic changes in cerebral blood flow and neural activation within prefrontal cortical regions.
The retrieved literature directly supports the claim that PTSD recovery correlates with changes in prefrontal cortex blood flow or activation. Specifically, papers [0], [1], and [7] report longitudinal or treatment-related changes in prefrontal perfusion and functioning that correspond with symptom improvement or recovery. No papers refute this relationship.
