title: Temporal sequence of frequency specific and nonspecific effects of flickering lights upon the occipital electrical activity in man.
abstract: Human subjects were exposed 10 times to light flicker for a period of 10 sec, being altered with equal non-flicker periods. Four flicker frequencies were studied: the resting alpha frequency, twice the frequency, and 14 and 6 c/sec, which are both unrelated to alpha rhythms. The effect of flicker stimulation upon the occipital EEG was quantified in terms of integrated values per band over an epoch of 10 sec using a Walter-type frequency analyzer.
