Pre- and post-neurofeedback intervention correlations for the PTSD experimental group and sham-control group (voxel-wise pFWE < 0.05, k = 10). * Denotes region-of-interest analysis also evaluated at the same error protection rate. Acronyms: DMN = default mode network, SN = salience network, CAPS = clinician administered PTSD scale (PTSD severity), NFB = neurofeedback.
