Fig. 4From: Abnormality of visual neuromagnetic activation in female migraineurs without aura between attacksSource location of V2: Magnetic source imaging (MSI) shows the source of activation of neuromagnetic response evoked by a visual stimulus in 5–30 and 100–300 Hz frequency bands in a migraine subject (migraine) and a control (control). The neuromagnetic activation evoked by a visual stimulus is mainly localized in the contralateral primary visual cortex (cPVC) in all migraineurs and controls, activation in regions beyond contralateral primary visual cortex (RBcPVC) was also noticed in some of the migraineurs and controls. Those areas included extensive visual cortex and parietal/temporal areasBack to article page
