RPE effects in the fMRI-analysis
| Contrast | Region | Hemisphere | Cluster size | x | y | z | Z-score |
|---|---|---|---|---|---|---|---|
| RPE | vmPFC | Bilateral | 186 | −5 | 44 | −12 | 6.50 |
| 156 | −2 | 57 | −5 | 6.14 | |||
| PCC | Bilateral | 184 | −2 | −52 | 19 | 5.89 | |
| −RPE | AI | Right | 172 | 36 | 18 | 0 | 6.25 |
| dmPFC | Bilateral | 358 | 6 | 20 | 48 | 6.23 | |
| AI | Left | 27 | −30 | 23 | −3 | 5.92 |
RPE significantly (de-)activated vmPFC, dmPFC, PCC, and the AI. All these areas were entered into the fMRI-informed EEG analysis to determine the unique time courses of vmPFC and dmPFC. All coordinates are reported in MNI space. Areas reported at p < 0.05 FWE-correction, k > 20. RPE, Areas that increase activity with increasing RPEs; −RPE, areas that increase activity with decreasing RPEs.
