The structural differences in gray matter between migraineurs without aura and healthy controls. a, compared with controls, the migraineurs without aura exhibited significantly increased gray matter volume in bilateral cerebellar culmen (lobule I-IV and lobule V). b, cortical thickness was significantly thicker in the left LOTC, and significantly thinner in the right INS in migraineurs without aura than in the healthy controls. c, the GI were significantly increased in the left POG, the SPL and the right LOcC, and decreased in the left DLPFC in the migraineurs.
