Appendix 1—table 5. Regions used for small volume correction.
| region of | peak voxel (mm) | reference for | ||
|---|---|---|---|---|
| small volume correction | x | y | z | peak voxel |
| rFPC (right frontopolar cortex) | 27 | 57 | 6 | Daw et al., 2006 |
| lFPC (left frontopolar cortex) | −27 | 48 | 4 | Daw et al., 2006 |
| rIPS (right intraparietal sulcus) | 39 | −36 | 42 | Daw et al., 2006 |
| lIPS (left intrapareital sulcus) | −29 | −33 | 45 | Daw et al., 2006 |
| rAIns (right anterior insula) | 32 | 22 | -8 | Blanchard and Gershman, 2018 |
| lAIns (left anterior insula) | −30 | 16 | -8 | Blanchard and Gershman, 2018 |
| dACC (dorsal anterior cingulate cortex) | 8 | 16 | 46 | Blanchard and Gershman, 2018 |
Note: Each small volume correction used a 10-mm-radius sphere around the listed voxel coordinates, which mark brain regions that have previously been associated with exploratory choices.
