Figure S1. Comparison of prefrontal (PFC), ventral striatum (VS), and orbitofrontal (OFC) regions-of-interest (ROI). Left panel presents statistical maps of for each ROI. Middle panel presents scatterplots, provided for descriptive purposes, indicating the correspondence between age and the neural peer effect (βpeer - βalone) within each ROI. Right panel presents, for each age group, activity observed for GO relative to STOP trials. Estimated activity was averaged over the 4 peak voxels in each ROI. Error bars indicate standard error of the mean.
