Fig. 2: Alprazolam modulates persistence energy during recall of threatening faces.

A Boxplots show persistence energy for the emotion identification task, grouped by emotion category; P Placebo; A Alprazolam. B Boxplots show persistence energy for emotion memory task, grouped by emotion category. We observed a significant group×drug interaction in the threat condition (γ11 = −0.048, p = 0.026, df = 73); P Placebo, A Alprazolam. C Average spatial maps of control impact for threat emotion identification, shown on surface renderings of cortical and subcortical areas. D Average spatial maps of control impact for threat emotion identification, shown on surface renderings of cortical and subcortical areas. Parcels outside the imaging slab are colored gray.
