Thirteen migraine patients underwent visual stimulation with left hemifield checkerboard reversals, with their right eye covered. Single dipole modelling of the right visual cortical activation at ∼ 100 ms (P100 m) after stimulus onset demonstrated a significantly shorter peak latency and a trend for increased amplitude in migraine patients than their sex- and age-matched controls. Our findings add evidence to the visual dysmodulation of migraine sufferers.
