Figure 11. Histogram of group-level whole-brain t-statistics on the experimental rsfMRI dataset.
Distribution of voxel-wise t-statistics using (a) RSMFC and (b) GSReg. In GSReg, the distribution shifts towards negative values, e.g. the wide plateau between t-statistics of −5 and 0. In contrast, the mode of the distribution is centered at zero in RSMFC. RSMFC = random subspace method functional connectivity. GSReg = global signal regression method.
