Figure 3. Correlation map between subjective pain scores and brain activations.
(Adjusted for response duration -data-driven analysis- including all individuals). Display threshold, P<0.01, 10 voxels. R indicates right hemisphere. The plot illustrates the correlation at peak activation in anterior cingulate cortex (ACC) (r = 0.82, P<0.0001 and adjusted r2 = 0.66). A.u., arbitrary units. Red and blue dots correspond to patients and control subjects, respectively. The names of the regions are shown in Table 3.
