Background.—Migraineurs with visual aura are highly susceptible to illusions and distortion particularly sensitive a pattern of regularly spaced parallel lines or stripes. Purpose.—To determine whether the high degree susceptibility in migraineurs is associated hyperneurological activity occipital cortex. Methods.—In order investigate any relationships among neuronal activity, spatial frequency square‐wave gratings, self‐described distortion, we investigated psychophysical responses gratings nonheadache controls. Results.—Square‐wave provoked various types induced hyperneuronal response cortex aura, that strongly depended upon stimulus frequency. Conclusion.—The consistent general cortical hyperexcitability migraine.
