Table 2. Univariate contrast between internal- and external-perspective tasks (p<0.001, cluster-level FWE-corrected p<0.05 across the whole cortex).
| Anatomical label | Center MNI coordinate* | Cluster size | ||
|---|---|---|---|---|
| X | Y | Z | Number of voxels† | |
| Internal > external-perspective task | ||||
| Supplementary motor area (R) | 10 | –22 | 69 | 34 |
| Supramarginal gyrus (R) | 61 | –36 | 26 | 98 |
| Internal > external-perspective task | ||||
| Precuneus (R) | 4 | –61 | 45 | 79 |
| Retrosplenial cortex (R) | 16 | –56 | 19 | 45 |
| Superior frontal gyrus (R) | 27 | 12 | 56 | 95 |
| Angular gyrus (R) | 45 | –66 | 30 | 78 |
The average Montreal Neurological Institute coordinates of all the significant voxels of each cluster. The precuneus and the retrosplenial cortex were connected as one cluster under the threshold p<0.001 (z>3.09). In this case, we increased the threshold to the point when the precuneus and the retrosplenial cortex were separate (z > 3.3) and calculated the average coordinates of each cluster.
The voxel size is 3 × 3 × 3 mm3.
