Patient versus control FC_Δ effects. 3D rendering (Madan, 2015) of whole-brain t-statistical maps comparing FC_Δ for (A) dystonic tremor (DT) versus controls (CON) and (B) essential tremor (ET) versus controls (bottom). The x-axis denotes the seed region of interest in the SMC/IPL, GPi, VIM, and dentate nucleus (DN). The y-axis in each panel denotes the location of the seed region of interest in the left (L) and the right (R) hemispheres. In each panel, positive (red-orange) clusters, denote significantly increased FC_Δ with the seed region of interest in the patient group (i.e. dystonic tremor or essential tremor) relative to controls, whereas negative (blue) clusters, denote significantly reduced FC_Δ with the seed region of interest in patient groups relative to controls (P < 0.05 FWER-corrected).
