The maximum flicker frequency was determined over a 5+6-log-unit range of retinal illuminance for a stimulus configuration designed to isolate the linear response from long-wavelength (R) cones. For a particular retinal location, the data conformed to the Ferry-Porter law and departed significantly from the predictions of the diffusion equation. The slope of the function was an invariant characteristic and was unaffected by stimulus intensity or area, modulation waveform, or modulation… CONTINUE READING
