Abstract

Stimulation of dark-adapted rods can shift the hues associated with specific wavelengths throughout the spectrum: Rods exert a green bias (strengthen green relative to red) at longer wavelengths and a blue bias (strengthen blue relative to yellow) at short-to-middle wavelengths. A third rod influence at shorter wavelengths is more complicated because it has been shown to reverse direction with change of stimulus duration. Thus, for 30-ms stimuli, rods exert a green bias like that observed at longer wavelengths. However, for 1-s stimuli, rods exert a red bias that is observed nowhere else in the spectrum. We examined the latency (time course) of rod hue biases by measuring the shifts of the three spectral unique hues under dark-adapted versus bleached (cone plateau) conditions. The rod green bias at unique yellow (mean 10 nm) and, in contrast to some prior studies, the rod blue bias at unique green (mean 21 nm) were not systematically affected by test stimulus duration. A quick rod green bias (mean 5 nm) was shown at unique blue for two of three observers but was dominated by a slower rod red bias (mean 11 nm) after 30–50 ms of rod stimulation. These opposing rod influences may reflect competing effects of rod signals on ML-cone and S-cone pathways.
