Figure 3. Whole-brain results.
Note. DMPFC = dorsomedial prefrontal cortex; TPJ = tempoparietal junction; PG = precentral gyrus. fMRI results for the interaction contrast testing for activity associated with four-load (vs. two-load) social working memory trials relative to four-load (vs. two-load) non-social working memory trials. Panel A depicts clusters of default network hyperactivation in response to four-load social working memory trials in the PTSD group. Panel B presents parameter estimates from each of these clusters for each condition within each group (PTSD vs. trauma-exposed controls).
