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).
