|HBM_21513_sm_SuppFig1.tif||610K||Supplementary Figure 1. T-statistic maps obtained from the regression of RVT with all voxels in the brain, thresholded at p<10-6 uncorrected (equivalent to appx. p < 0.05 after Bonferroni correction across voxels, not taking into account the multiple comparisons across lags), for all subjects (S1 - S5). Maps show the minimum/maximum T-statistic across all 33 regressions, for every other slice (10 out of 20 slices shown). For subject S3 (lower panel) the T-statistic map after RVT correction is also shown.|

In certain instances more than one network can be seen (e.g. S4 panel C: n3,n2, S5 panel A: n1,n2). The maps were spatially clustered with minimum cluster size of 5 voxels.|

Seed voxels were located in M1 for MN, eVis (n2:VN), PreCu (n3:DMN) and IPS (n4:DAN). Results are illustrated for 5 slices selected as marked in the sagittal view.|
