ACN: anterior cingulate; AMY: amygdala; MED: medial prefrontal cortex; MID: midbrain; 1TC: one-tissue compartment kinetic model (iterative fit); 1TCNI: One-tissue compartment kinetic model (noniterative fit); VST: ventral striatum.

Results are displayed for representative ROIs, but the mean and standard deviation given in the last table row is taken over all ROIs.
