Mean ReHo maps within the MNE, non-NE and healthy control groups (P<0.01, FDR corrected).

<p>The PCC/precuneus, MPFC, IPL, bilateral middle/inferior temporal gyrus, cuneus and thalamus exhibit significantly higher ReHo values than the global mean ReHo value within each group, and with a gradually decreasing tendency from normal controls, non-NE to MNE. MNE = minimal nephro-encephalopathy; non-NE = non-nephro-encephalopathy; ReHo = regional homogeneity; FDR = false discovery rate; PCC = posterior cingulate cortex; MPFC = medial prefrontal cortex; IPL = inferior parietal lobe.
