Clusters from whole-brain positive correlation of caudate D2/D3 receptor availability (BPND) with Successful Stop versus Go fMRI contrast
| Brain region | Hemisphere | Voxels | Maximum Z-statistic | x | y | z |
|---|---|---|---|---|---|---|
| Caudate | L/R | 1173 | 3.49 | 12 | 16 | 8 |
| Thalamus | R | 2.98 | 6 | −2 | 6 | |
| Superior frontal gyrus | R | 496 | 3.12 | 22 | 48 | 32 |
| Frontal pole/lateral orbitofrontal cortex | R | 823 | 3.40 | 50 | 42 | −8 |
| Rostral anterior cingulate/superior frontal cortex (medial portion) | L/R | 1099 | 3.78 | 0 | 48 | 38 |
| Inferior frontal gyrus, pars opercularis/anterior insula | L | 497 | 3.56 | −42 | 16 | −2 |
| Middle frontal gyrus | L | 504 | 3.47 | −42 | 20 | 44 |
| Cerebellum | L/R | 1984 | 3.76 | −6 | −84 | −32 |
L, Left; R, right. Z-statistics and x, y, and z MNI coordinates (mm) are from the location of peak voxel within each cluster (or local maxima within clusters, indicated by indented regions). Z-statistic maps were whole-brain cluster-corrected at Z > 1.96, p < 0.05. No regions showed significant clusters for negative correlation with BPND.
