Top panel: Relatively increased neural reactivity after overt as compared to covert treatment with escitalopram in the bilateral posterior cingulate cortex as well as the left mid temporal and inferior frontal gyri, measured during the emotional face-matching paradigm. Lower panel: Interaction plots illustrating the neural changes in the four implicated cortical regions from pre to posttreatment in the overt (blue bars) as compared to the covert (red bars) group. Error bars reflect the standard error of the mean. AU refers to arbitrary units and BA refers to Brodmann area.
