  • Title: Spectral analysis of photic stimulation in migraine.
    Author: Simon RH, Zimmerman AW, Tasman A, Hale MS.
    Journal: Electroencephalogr Clin Neurophysiol; 1982 Mar; 53(3):270-6. PubMed ID: 6174301.
    Abstract:
    In seeking an electrophysiologic discriminator of migraine, we applied computer technology to power spectral analysis of the EEG with photic stimulation. In 11 normal volunteers and 11 migraineurs (both classic and common) we were able to classify all migraineurs and misclassified only one normal based on the spectral analysis. The discriminator contained 5 elements: the increased driving power of migraineurs with photic stimulation at 24 flashes/sec, 34 flashes/sec, and 38 flashes/sec; and the increased power in the alpha band in both parietal and occipital leads at 20 flashes/sec. Power spectral analysis in conjunction with photic stimulation may provide the necessary data for effective discrimination of migraine from non-migraine states.
