Neurophysiological evidence of increased cortical reactivity in migraine.
Cortical reactivity in migraine can be studied with evoked potentials. The majority of the evidence shows increased reactivity in migraine, which may be due to abnormal inhibition. At present, the techniques are not useful for diagnosis. Discrepancies between reports may be due to fluctuations in reactivity over time. Documenting this changing reactivity requires refinement of analysis techniques.
