Regional homogeneity (ReHo) maps in migraineurs without aura and healthy controls and the differences between groups. a The ReHo maps of each group were obtained by one-sample t test (FDR corrected, P = 0.001). b When comparing controls, the migraine patients exhibited significantly increased ReHo values in the bilateral precuneus/PCC, pons and trigeminal nerver entery zone. c The mean ReHo z-scores were extracted within the significantly altered brain area of each subject. There were no significant differences in ReHo between the female and male migraineurs without aura. d The ReHo z-score of the trigeminal nerver entery zone was positively correlated with the HIT-6 score (r = 0.43, p < 0.05). HC, healthy control; M, migraineurs without aura
