1950 H. Gastaut in Electroencephalogr. & Clin. Neurophysiol. 2 250/1 In the EEG is a burst of very large amplitude rhythmic spikes of a frequency equal to that of the flashes; these are bilateral and synchronized, and appear predominantly in the precentral and frontal regions where they can in fact be localized... These spikes are sometimes quite pure and thus constitute the complex for which we have proposed the name ‘polyspike’.
