Figure 3: Average BOLD signal of each meditation state contrasted with J2 is shown on the -axis, with a separate line for each ROI. The -axis denotes each state from rest to AC to J2–J5. The mean SE of the signal contrasts averaged over the ROIs and states was ± .3. Note the high correlation between the lines in (a) and the steep increase in “NAc” at J2 in (b) (J1 was not recorded due to head movement artifacts).
