Correlation analysis of the ΔReHo/ΔfALFF and Δpain duration (PHN-HZ). ΔReHo values of the left cerebellum (i.e., the inferior semi-lunar lobule and the cerebellum posterior lobe) were positively correlated with pain duration between the two MRI scans (A, B), while those of the left posterior- and middle-cingulated gyrus were negatively correlated with pain duration (C, D). In addition, the ΔfALFF values of the left occipital lobe (Calcarine_L (aal) and Occipital_Sup_L (aal)) were positively correlated with pain duration (E, F). ΔReHo = ReHo (PHN) - ReHo (HZ); ΔfALFF = fALFF (PHN) - fALFF (HZ); Pain duration = pain duration at the second MRI scan (the PHN period) - pain duration at the first scan (the HZ period). Pearson correlation analysis, n = 12.
