Mean cortical thickness combining right and left hemispheres for each ROI across groups (n=28 per group). Manually mapped SMC subregions refer to corresponding regions described in DaSilva et al. (8). SMC: sensorimotor cortex, PCS: precentral sulcus, MWA: migraine with aura, MwoA: migraine without aura, V3A: visual cortex area V3A, MT+: visual cortex area MT+.
