Human ERG in response to double flashes of light during the course of dark adaptation: a Fourier analysis of the oscillatory potentials.

After adaptation to light the recovery in the dark of the adaptometric visual threshold and E R G (Elector Retina Gram) were studied in response to strong light flashes of short duration. Strong light flashes of short duration facilitate the regeneration of oscillatory potentials, probably by inducing transient neural activity in the inner retinal lagers
