“…Despite the abundant literature on photosensitivity and photosensitive epilepsy (Bickford et al, 1952;1953;Livingston, 1952; Gastaut et al, 1958;Langergren and Hansen, 1960;Maudsley, 1961; Pallis and Louis, 1961;Bickford and Klass, 1962;Pantelakis et al, 1962;Bower, 1963;Charlton and Hoefer, 1964;Foster and Campos, 1964; Gastaut and Tassinari, 1966;Jeavons and Bower, 1966;Jeavons andHarding, 1970, 1975), there are very few reports on photosensitivity in black Africans. Gallais et al (1951) and Mundy Castle (1953) observed a significantly greater incidence of nonreaction to rhythmic photic stimulation during an EEG in black Africans than in Caucasians.…”
