Regions small volume corrected (SVC) at p < 0.05 FWE with a 10 mm sphere using a priori independent coordinates: Krueger et al., 2007; Zahn et al., 2009; King-Casas et al., 2005.

Note: Although an a priori ROI was used to determine the VTA, given the small, tightly clustered nature of the nuclei, it is difficult to fully rule out that some activation may also be within the PAG. Higher resolution imaging should be used to confirm these results.
