[Effects of various regimes of rhythmic photostimulation on fatigue and related parameters of the psychophysiological status in humans].

In randomised blind study with active placebo control in humans, rhythmic photostimulation of 77 Hz frequency did not elicit any fatigue or negative psychophysiological events as opposed to 50, 60, 100 Hz frequency. This and other findings are to be considered in designing rational systems of cinema projection and PC monitors.
