Node strength in PTSD + vs. PTSD- patients in the hippocampus, broadband (1–45 Hz). The three boxplot columns represent the resting state node strength the hippocampus calculated respectively: with all other brain regions (“all connections”), within the involved network (“inside involved network”), and between each involved region and other regions that are supposed not to be involved in PTSD (“involved-non-inv”). (A) total node strength of the hippocampus located ipsilaterally to the EZ in PTSD- subject (light yellow) compared against PTSD + subjects (dark yellow). (B) total node strength of the hippocampus contacts located contralaterally to the EZ in PTSD- subject (light yellow) compared against PTSD + subjects (dark yellow). P-values were coded as follows: **p < 0.01, ***=p < 0.001.
