Figure 3.

A: Range of the number of activated voxels of all subjects at different statistical thresholds. Number of activated voxels is shown in x‐axis and the statistical level in y‐axis. Each point represents the activated volume of one subject. B: Illustration of the common implicated voxels (the PO maps) across subjects at different statistical thresholds. The statistical thresholds (P uncorrected), listed from bottom to top, varies from P < 0.05 to P < 0.0000001. The colour scale on the bottom of the figure encodes the degree of overlap (e.g., voxel with 50% indicates that it was observed in half of subjects). Left hemisphere = left side of the images.
