Diffusion tensor imaging (DTI) metrics of bilateral thalami of healthy controls (HC), migraine with exclusively visual aura (MA) patients, and migraine with complex neurological aura (MA+) patients scanned between attacks. Data are expressed as means ± SD; * MA + vs. HCs p < 0.025, ** MA + vs. HCs and vs. MA p < 0.025
