Value‐related increase in the inverse functional interaction between the VMPFC and the right ventral striatum with increasing value of the foregone reward option during the “desire‐reason dilemma” in the HI group. (A) Parametrical increase in the inverse connectivity between VMPFC and ventral striatum with increasing value of conditioned (rewarding) nontargets that had to be rejected in the “reason context” (dilemma‐related reductions in prefrontostriatal connectivity are displayed on a coronal slice of the MNI template, color bar shows associated t‐values; see also Table V). (B) Contrast values of the psychophysiological interaction parameters from the ventral striatum in the HI and in the LO group (in the comparison of individual bonus values presented in the “reason context” vs. the “desire context”). Only in HI individuals the parameter estimates of functional interaction strength between the VMPFC and the ventral striatum exhibited a significant decrease with increasing reward value in the “reason context” relative to the “desire context”.
