Displays cluster centroid ( 𝑥 -, 𝑦 -, and 𝑧 - MNI coordinates), maximum 𝑡 -statistic within the cluster, 𝑃 value (unadjusted) of the maximum 𝑡 -statistic, cluster size in number of contiguous voxels, and permutation test-based cluster 𝑃 value. The cluster 𝑃 -value compares the size of each suprathreshold cluster to the permutation distribution of the largest cluster, thereby accounting for multiple comparisons. Only results from clusters of 100+ voxels shown.
