Table 2. Significant Differences in Whole-brain Activity Between the Saline and Heroin Conditions.
| Contrast | Treatment | Region | MNI coordinates (x, y, and z) | T-value at voxel level | Cluster size |
|---|---|---|---|---|---|
| No–Go vs Go | Saline>heroin | Right IFG | (52, 14, 34) | 3.23a | 11 |
| Oddball vs Go trials | Saline>heroin | Right IFG | (60, 26, 24) | 3.28a | 13 |
| No–Go vs oddball trials | Saline>heroin | / | / | / | / |
Note: We found no significant voxels that were FWE cluster-level corrected across the whole brain at P<0.05.

Survives peak and voxel-level correction for multiple comparisons after adjustment for small volume (FWE-corrected at P<0.05).
