Migraine is a primary headache disorder characterized by abnormal cortical activity acrossmigraine phases. However, less is known about electroencephalographic activity present duringasymptomatic periods of the migraine cycle or during resting-state conditions. Given the theorythat these testing conditions may reflect more permanent cortical states, the present studyexamined the interacting role of resting-state conditions (eyes-open vs. eyes-closed) andheadache diagnosis (migraine vs. control) on absolute band power across the EEG frequencyspectrum. In-line with previous research, we hypothesized that interictal periods of the migrainephase would be characterized by a difference in alpha frequency and an increase in slow-waveactivity compared to controls. We further predicted that group-related effects would differdepending on resting-state conditions. In general, slow-wave activity was greater in migriane compared to controls, although a significant interaction effect was obtained regarding fast-wavebeta power. Broad spectrum cortical differences between migraine and healthy controls arediscussed.
