The effects of test flash luminance and adaptation level on the latencies of the b-wave and the evoked optic lobe potential are described. There is a striking parallelism between the two activities. The b-wave arises shortly before the evoked potential for all but the very high test-flash luminances where the b-wave follows the tectal response by a narrow margin. The a-wave always precedes any optic lobe activity. Adaptation level, although influencing response amplitudes, has no appreciable effect on latencies.
