Figure 1.

Illustration of the sequence of the five functional scans. Pre‐VS: prior to the 25‐min visual stimulation; Post‐VS: after the 25‐min visual stimulation; and VCA: visual cortical activation. The 1‐min gap between the second and third scan was used to prepare and start the latter scan. The only difference between Experiments I and II is that, during the 25‐min visual stimulation, the stressful pattern was used in the former and the non‐stressful pattern was used in the latter, respectively.
