[Investigation of the brain reactiveness depending on the type of human intrinsically present electroencephalography]

While adopting the lighting flashes 9 Hz in frequency, and while the absence of the adopting the rythm reaction during the photostimulation conduction in majority of the patients examined the alpha-oscillations amplitude according to background electroencephalography constitutes 25-50 mcV; while adopting of the lighting flashes rythm with 6 and 12 Hz frequency--50-75mcV.
