 A cross sectional study to compare the best approach to migraineurs evaluation. For this, healthy individuals, after reading and signing the free and informed consent will be submitted to a single session to obtain the normal neurophysiological endpoints and thus compare with those obtained in individuals with migraineurs volunteers. All volunteers healthy and migraineurs will be submitted to a neurophysiological evaluation through transcranial magnetic stimulation TMS and electroencephalography EEG. A visual stimulation will be delivered during the assessment of habituation through visual evoked potential volunteers VEP-habituation and the following measures will be evaluated before and after visual stimulation: i Motor Evoked Potentials MEP; ii Motor Threshold MT; iii Short Interval Cortical Inhibition SICI; iv Intracortical Facilitation lCF and v Phosphene Threshold PT.
