Results of the fMRI-constrained source analysis. Post-hoc t-tests, indicating significant differences between OG and PG for root mean square values of regional source moment activities revealed from fMRIconstrained source analyses applied on differences waves between high-risk and lowrisk, and win and lose trials discrete time windows related to ERP-effects (Figure 2). Sources which are included in the analysis according to the state of model fit are grey-shaded. Black boxes show trend to significant (regional source 3 at 100-150 ms during reward processing; p = 0.067) and significant (all other black boxes; p < 0.05) post-hoc t-tests.
