Cortical function abnormalities in migraine: neurophysiological and neuropsychological evidence from reaction times and event-related potentials to the Stroop test.
Cortical hyperexcitability was studied in migraine patients using reaction times (RT's) and Event-Related Potentials (ERP) to the Stroop test. We found a slower RTs in patients if compared to controls, supporting the hypothesis of a mild cortical functions impairment even in interictal periods in this group of patients.
