Before and after the neurofeedback sessions, participants completed tasks to assess their changes in control over amygdala activity at the following timepoints: pre-NF, post-NF, and 30 days post-NF. Participants completed 4 amygdala control task runs during each of these individual imaging sessions. Each control task run lasted 5 minutes. In these runs, there was a provocation period during which participants heard a minute-long audio clip designed to induce recall of a specific traumatic event. This was followed by a downregulation block when they were cued by a blue down-arrow to decrease activity in their amygdala. These two blocks were embedded in 1-back task blocks (30 s per block) that helped to distract subjects and to prevent anxiety associated with the trauma from affecting the resting periods at the beginning and end of the run (see Fig.
