Figure 7

Cluster size exclusion applied to surface-based group statistics. Group analysis t-statistics (real data, n = 12 subjects) are displayed on a cortical surface mesh. A. Unthresholded t-statistics. B. t-statistics thresholded at p < 10−2, before (left) and after (right) clusters smaller than the simulated cluster size threshold were excluded. In C, a threshold of p < 10−3 was applied. In B and C, the multiple comparison corrected p-value was 0.05 after cluster exclusion for the surface-based statistics. D. Multiple ROIs defined with sliding threshold cluster exclusion and subsequent cluster growth. Automatically generated cortical surface ROIs are shown in different colors.
