Temporal Summation of Light by a Vertebrate Visual Receptor

Using aspartate to isolate mass receptor-activity, we have investigated the reciprocity of flash intensity and flash duration in determining the response of the frog's cone receptor. The duration over which reciprocity holds decrease with increases in either flash energy of ambient light intensity. These findings parallel those of human psychophysical experiments.
