Chiasm responses to 1-ms LED flashes continuously delivered at rates of
1 and 3 Hz. Each trace represents the average of about 50 samples, 750
ms in duration timelocked to a flash. At the repetition rate of 1 Hz,
the histogram has a duration of about 350 ms and displays typical
B/, B−, and C/ deflections. The 3-Hz responses resemble
the 1-Hz versions, which shows that this retina continuously created
separate, complete histograms of three photoreceptor bleach patterns
every second (Rat J37).
