Figure 3.

Voxelwise analysis showing regions that show trial-related activity (regardless of condition), p < 0.05 corrected for multiple comparisons. Results are shown in neurological orientation (with left presented on the left). Numbers above axial slices denote Z dimension of MNI space. Note bilateral activity in the anterior insula, supplementary motor area, and intraparietal cortex, with a largely left-lateralized somatosensory response (probably reflecting the fact that participants made right-handed responses).
