The effect of light deprivation on the flickering B-wave

The effect of light deprivation on the flickering beta-wave was investagated. Results indicate that the flickering beta-wave is extremely reduced in the eye light-deprived for 14 to 20 days relative to the normal eye. The ratio of the second beta-wave (in a series of flickering beta-waves) to the ratio of the first beta-wave appears relatively unaffected by light deprivation, but the ratio of the fourth beta-wave to the first is significantly affected by light deprivation. The effect of light deprivation on the beta-waves evoked by a 13.4 milliambert flickering light is greater for beta-waves evoked later in the series than for beta-waves evoked earlier in the series.
