| M1FT | Average activation cluster from finger-tapping pre-TDCS (FTpre) |
− 38, − 24, 60 Cluster size = 325 voxels |
| M1-S1anat | Based on probabilistic atlas (FSL Juelich) areas BA4a, BA4b BA3a, BA3b and BA6 for the left hemisphere | |
| Abbreviation | Definition | Coordinate of center of sphere |
|---|---|---|
