Mean ± SD over all ROIs for λ and μ are −39.97 ± 2.36 and 34.71 ± 11.49, respectively. Statistical P values of t test for difference between mean of λ (−39.97) and λ of each ROI are 0.34, 0.04, 0.43, 0.08, 0.30, 0.24, 0.06, 0.17, 0.14, 0.63, 0.57, 0.75, 0.09, and 0.56 for caudate, putamen, thalamus, lateral temporal, mesial temporal, orbital frontal, prefrontal, superior frontal, occipital, parietal, anterior cingulate, posterior cingulate, pons, and white matter ROIs, respectively.
