Figure 2.

Time-courses of activation in the right amygdala (top) and left hippocampus (bottom) displaying a significant Group × Phase interaction. The posttraumatic stress symptoms (PTSS) group time-course is shown in red and the HC group is shown in green. The x-axis is seconds, and the early phase (0–12 s) and late phase (12–24 s) are indicated (both shifted 6 s forward to account for the hemodynamic lag). For the right amygdala, the PTSS activation is greater than the HC particularly in the early phases of the angry and fear blocks. For the left hippocampus, PTSS activation is greater during early and late phase of the angry blocks, but less during the late phase of the happy and sad blocks.
