“…In a separate investigation, the effects of rod–cone interaction on reaction time mediated by chromatic and luminance pathways were studied. Lateral rod–cone interactions increase cone-mediated RTs with the strongest rod–cone interactions in a dark surround ( Zele et al, 2014 ). Reaction time has been explored as a basis for developing a real world, performance based mesopic luminous efficiency functions ( He et al, 1997 , 1998 ; Walkey et al, 2005 , 2006a , b ) with the assumption that reaction time is signaled via the MC pathway ( He et al, 1998 ).…”

Evidence has accumulated that rod activation under mesopic and scotopic light levels alters visual perception and performance. Here we review the most recent developments in the measurement of rod and cone contributions to mesopic color perception and temporal processing, with a focus on data measured using a four-primary photostimulator method that independently controls rod and cone excitations. We discuss the findings in the context of rod inputs to the three primary retinogeniculate pathways to understand rod contributions to mesopic vision. Additionally, we present evidence that hue perception is possible under scotopic, pure rod-mediated conditions that involves cortical mechanisms.

“…This result might be caused by the rods that raise the sensitivity in relation to the cones in dark regions. [19][20][21] In the conditions of luminance higher than 1 cd/m 2 , the best sensitivity appears in the region in which the reference and surround luminance conditions are the same.…”

In order to provide practical and useful data for display design, border detection with various levels of surround luminance from 0.001 to 500 cd/m2 is investigated. The results indicated that luminance difference for border detection exhibits a monotonically increasing curve against the reference luminance on a logarithmic scale. To compare the luminance difference curves for different surround luminances, the results were converted to contrast threshold curves against the reference luminance that are U‐shaped on a logarithmic scale. These contrast thresholds, however, are higher than those of the grayscale standard display function curve. The causes of the difference between the contrast threshold curves of our study and the grayscale standard display function curve are the adaptation conditions and stimulus size, as well as the difference in criteria between the detection of a border and the detection of non‐uniformity. Finally, the necessary number of gradation levels for border detection under various surround luminances is calculated and found to be at least double the current number of levels (256).

“…We examined only one light level from the broad mesopic range extending over an illuminance range of 10 3 -10 4 in our previous study (Yoshimoto & Takeuchi, 2013). However, motion information processing might be different even under mesopic vision because of the complex nature of cone-rod interaction and the different amount of rod contribution across light levels (Bloomfield & Dacheux, 2001;Cao, Pokorny, Smith, & Zele, 2008;Stockman & Sharpe, 2006;Zele & Cao, 2015;Zele, Maynard, Joyce, & Cao, 2014). Thus, in Experiment 1 of the present study, we measured the strength of negative motion priming at various mesopic light levels following our previous experimental method in order to examine the effect of light levels on the integration of spatiotemporally separated visual inputs.…”

Mesopic and scotopic vision extend over an illuminance range of 106. The goal of the present study was to determine the effect of decreasing light level on the underlying motion mechanism that integrates spatiotemporally separated motion signals. To accomplish this, we took advantage of the phenomenon of visual motion priming, in which the perceived direction of a directionally ambiguous test stimulus is influenced by the directional movement of a preceding priming stimulus. After terminating a drifting priming stimulus, a 180° phase-shifted grating was presented as a test stimulus. The priming and test stimuli were separately presented to the central and peripheral retinas, respectively. The participants judged the perceived direction of this test stimulus at various light levels from photopic to scotopic levels. We found that the effects of motion priming disappeared over 1 log unit of mesopic light levels. When the test stimulus was presented before the offset of the priming stimulus to compensate for the temporal delay in the rod pathway or when both stimuli were presented at the same location in the periphery, a motion-priming effect appeared at mesopic light levels. These results suggest that different temporal characteristics between the cone pathway and rod pathway disturb the function of the putative motion mechanism responsible for the spatiotemporal integration of motion signals, which leads to specific modulation of motion perception over a wide range of mesopic vision.
