Fig. 5. A , Positive blood oxygenation level dependent signal correlation with numerical rating scale (NRS) at incision 4.5–10 min after incision (second-level analysis [SPM5], uncorrected P = 0.005, 10 voxels). A strong activation of the contralateral amygdala can be depicted (x =−24, y = 0, z =−24). Illustrative scattergram of positive correlation between the activity of the contralateral amygdala (x =−24, y = 0, z =−24) in a region of interest analysis and NRS scores at incision.
