Changes in the response characteristics of the flash electroretinogram (ERG) of the human cone system were studied during the time course of adaptation to a cone-isolating ganzfeld background. During light adaptation, the amplitudes of the b- and i-waves increased, while the implicit time of the b-wave decreased. The amplitude of the a-wave and the implicit times of the a- and i -waves did not change systematically during light adaptation. Luminance-response functions for b-wave amplitude were obtained at discrete times following background onset and were analyzed using the hyperbolic equation R/Rmax= Ln/(Ln+ Kn). The increase in b-wave amplitude was characterized by increases in Rmax, K, and n. The decrease in b-wave implicit time was of a similar magnitude at all flash luminances. The amplitude increase of the i-wave only occurred at moderate flash luminances. The results provide a basis for optimizing the clinical recording of cone-isolated single-flash ERGs.
