Scatterplots depicting relationships between PTSD symptom severity and Habituation (difference in responding between Learning Block 1 and Learning Block 2) in the left anterior insular cortex (AIC) (A) and dorsomedial prefrontal cortex (dmPFC) (B). These ROIs were taken from the conjunction of clusters identified in the omnibus Habituation x PTSD symptom x Estradiol analysis (Figure 2A above) and the Habituation x PTSD symptom analysis among just the participants with low estradiol, determined by a median split.
