The scotopic band: primate detailed scotopic vision and perceptual uncertainty

This paper identifies a scotopic preferred-processing pathway in primates that relocates the scotopic center based on light intensity and perceptual uncertainty.

Individual variation of the dark-background-contingent upshift of gaze: effect of past habituation

The paper examines individual differences in gaze upshift when monkeys are exposed to dark backgrounds, finding that prior training in light or dark conditions significantly affects the magnitude of the response.

Monkeys use the rod-dense retinal region rather than the fovea to visually fixate small targets in scotopic vision

The paper shows that monkeys fixate small targets in scotopic vision by directing the fovea above the target, aligning the image with the locus of maximal rod density rather than the fovea.
