Visual stress–induced migraine aura compared to spontaneous aura studied by magnetoencephalography

Abstract

DC MEG shifts, similar and complex in waveform, were observed in visually induced migraine with aura patients similar to spontaneous aura but not controls. Multiple cortical areas were activated in visually induced and spontaneous aura patients. In normal subjects activation was only observed in the primary visual cortex. Results support a spreading depression–like neuroelectric event as the basis of migraine aura that can arise spontaneously or be visually triggered in widespread regions of hyperexcitable occipital cortex.
