Whole-brain theta connectivity time-series and the temporal evolution of functional network differences between PTSD and control groups.

<p><b>(A)</b> The PTSD group show elevated whole-brain theta coherence during the Intra-dimensional task (<i>top left panel</i>), particularly in the 100–300ms time window, which is evident in the regional connectivity maps below (<b>B;</b> all maps PTSD > control). In the Extra-dimensional set shifting task, the groups do not differ until the 300–400 ms time-window, when the PTSD show high-degree node differences, particularly in the right superior parietal lobule connecting to the right temporal and left frontal regions.
