Fig. 4.

Baseline comparisons between PTSD (n = 36) and healthy controls (n = 36) pre-NFB intervention (voxel-wise pFWE < 0.05, k = 10). All PTSD patients were grouped together at baseline and compared to age-matched healthy controls in terms of network connectivity. Red clusters correspond to increased network connectivity among PTSD patients as compared to healthy controls. Blue clusters would indicate increased network connectivity among healthy controls as compared to PTSD patients. Importantly, the PTSD experimental group and PTSD sham-control groups did not different significantly at baseline with regard to network connectivity. Acronyms: DMN = default mode network, ACC = anterior cingulate cortex, SMC = supplementary motor cortex, PTSD = posttraumatic stress disorder, NFB = neurofeedback.
