C‐waves of the rabbit ERG under urethane anesthesia were elicited by a Grass photostimulator during dark adaptation and under steady‐state conditions. After strong pre‐adaptation with light, the amplitude and time‐to‐peak of the c‐wave increased in parallel with the a‐ and b‐waves, reaching a maximum of 90–130 min. In the dark‐adapted steady‐state, repetitive stimuli at intervals ranging from 15 sec to 5 min elicited a stable c‐wave response except for a small dip in amplitude that occurred 2–6 min after initiating the shortest interval (15 sec) flashes. Although the changes in light and dark used in these experiments should have elicited shifts in the standing potential, no fluctuations of the c‐wave amplitude were evident with a time course corresponding to a light response of the standing potential.
