Signatures of migraine aura in high-density-EEG
CONCLUSIONS: Unequivocal signatures of spreading depolarization were not recorded with EEG on the intact scalp in migraine. The decrease in alpha-power contralateral to predominant visual symptoms is consistent with focal depression of spontaneous brain activity as a consequence of cortical spreading depolarization but is not specific thereof.SIGNIFICANCE: Cortical spreading depolarization is relevant in migraine, other paroxysmal neurological disorders and neurointensive care.PMID:38422969 | DOI:10.1016/j.clinph.2024.01.008
