fMRI connectivity changes during the emotional face processing task.
PTSD
Changes in connectivity of the left hippocampus to the left amygdala, pgACC and sgACC, and of the right insula to the left dlPFC, significantly correlated with changes in PTSD symptoms.For the above significant effects, there were no significant differences in changes in activation or connectivity over time between the PTSD and control groups (no group-time interaction).
