Emotion whole brain group vertex cluster analysis: Positive vs. fixation, negative vs. fixation, neutral vs. fixation.

Coordinates are presented for peak vertices within significant clusters of activation for surface analyses of the left and right hemispheres. Minimum significance for all vertices within a cluster were p = 0.001. Clusters were selected using permutation testing at p < 0.05. For context, Table 2 presents significant intergroup clusters for these contrasts; Fig 2 and S1 through S5 Figs show the corresponding cortical cluster maps. The clusters reported can be understood to span multiple functional regions [68]. That is, they are not limited to a single region, as reported by the maximal vertex. Abbreviations: ClusterNo—The cluster number within the analysis; Max—Maximum -log(p value) within the cluster; VtxMax—Vertex number for peak vertex; MNIX, MNIY, MNIZ—Montreal Neurological Institute 305 Atlas coordinates of maximum vertex; CWP—Cluster-wise p value; CWPLow, CWPHi—90% confidence interval for the CWP; NVtxs—number of vertices in cluster; Annot—Destrieux annotation for peak vertex.
