VBM and DBM analysis of the GMV. (A) VBM analysis revealed significantly decreased GMV in two clusters in patients with CTN compared with healthy controls. GMV atrophy was observed in the Temporal_Pole_Sup_R and Precentral_R (GFR, voxels P < 0.001, clusters P < 0.05). (B) DBM analysis revealed significantly increased GMV cluster (Temporal_Pole_Sup_L) in patients with CTN compared with healthy controls (GFR, voxels P < 0.001, clusters P < 0.05). CTN, classical trigeminal neuralgia; VBM, voxel-based morphometry; DBM, deformation-based morphometry; GMV: gray matter volume; GRF: Gaussian random field
