Figure 2. Displayed in red are clusters of voxels that showed a significant change in blood oxygen-level dependent (BOLD) activation from the congruent to the incongruent conditions of a Stroop stressor. These clusters of activation were revealed by random-effects region-of-interest (ROI) ANOVAs on BOLD activation within the orbitofrontal cortex, anterior cingulate, and the left and right insula. Gray shading depicts the anatomical boundary (mask) that was used to define each ROI. Results are overlaid on a canonical brain from the Montreal Neurological Institute (MNI).
