Electroencephalograms were registered in 5 clinically healthy undergraduates using the Neurovisor GMM device when a light stream with a frequency of 0, 3, 9, 21, 50 and 100 Hz was operated on the human visual apparatus with a coefficient of its ripple from 0 to 80%. It is shown that it is impossible to establish directly by the electroencephalogram a control of the pulsating action of the light flux on the bioelectric activity of the human brain, even at low frequencies.
