Figure 3. Left panel: Displayed in red is a cluster of voxels in the posterior cingulate cortex (Brodmann area 31; Talairach coordinates for peak activation voxel: X = 1, Y = –44, Z = 38) where high cardiovascular reactors showed an increase, but low reactors a decrease, in blood oxygen level dependent (BOLD) activation during the incongruent relative to the congruent condition of a Stroop stressor. Results are overlaid on a canonical brain from the Montreal Neurological Institute (MNI). Right panel: Plotted is the standardized incongruent-minus-congruent condition difference in posterior cingulate BOLD activation for both high and low cardiovascular reactors.
