Color and motion information are thought to be channeled through separate neural
pathways, but it remains unclear whether and how these pathways interact to improve …

Across the animal kingdom, color discrimination is achieved by comparing the outputs of
photoreceptor cells (PRs) that have different spectral sensitivities. Much remains to be …

Colour vision in humans is 'middling'at best, both figuratively and literally in the animal
visible spectrum of 300–750 nm. This comes as a surprise to many of us as we cannot …

Neural implementations of visual behaviors in Drosophila have been dissected intensively
in the past couple of decades. The availability of premiere genetic toolkits, behavioral …

Visual animals detect spatial variations of light intensity and wavelength composition.
Opponent coding is a common strategy for reducing information redundancy. Neurons …

Many insects exploit skylight polarization as a compass cue for orientation and navigation. In
the fruit fly, Drosophila melanogaster, photoreceptors R7 and R8 in the dorsal rim area …

The world in color presents a dazzling dimension of phenotypic variation. Biological interest
in this variation has burgeoned, due to both increased means for quantifying spectral …

A fundamental issue in biology is explaining the diversity of coloration found in nature. Birds
provide some of the best-studied examples of the evolution and causes of color variation …

An understanding of the natural history of color vision would provide significant insight into
the question of why we have color vision. Such information is not at hand, but studies of the …

Color and motion are used by many species to identify salient objects. They are processed
largely independently, but color contributes to motion processing in humans, for example …
