Fig. 9. Decomposition of vmPFC and DRN activity in value and choice.
a Effects of DVtotal in vmPFC/mOFC. b DVvalue, the part of DVtotal reflecting the value difference between chosen and unchosen options, correlated with a similar vmPFC area, but signal sizes were weaker. c Bayesian model comparison suggests vmPFC activity is better described by DVtotal than by DVvalue. ROIs were determined using a leave-one-out procedure. The dashed red line indicates an exceedance probability of 0.95 (n = 25 sessions; all MRI results cluster-corrected at Z > 2.6, p = 0.05).
