Scheme of the experimental procedures. The study consisted of two major parts: recordings with a conventional short-flash ERG (6.3 cd.s/m² flash strengths) (A) and with a sine wave modulation (B). The short-flash ERGs were performed with two separate protocols, which differed in the intensity of the adapting light. Each of the protocols consisted of a light and a dark adaptation period. (B) The flicker ERG response to sine-wave luminance modulation was divided into adaptation periods for high (25 cd/m²) and low (1 cd/m²) mean luminances.
