Color and polarization provide complementary information about the world and are detected
by specialized photoreceptors. However, the downstream neural circuits that process these …

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 …

Spectral information is commonly processed in the brain through generation of antagonistic
responses to different wavelengths. In many species, these color opponent signals arise as …

Background Color vision requires comparison between photoreceptors that are sensitive to
different wavelengths of light. In Drosophila, this is achieved by the inner photoreceptors (R7 …

Color vision is an important sensory capability that enhances the detection of contrast in
retinal images. Monochromatic animals exclusively detect temporal and spatial changes in …

Many insects use patterns of polarized light in the sky to orient and navigate. Here, we
functionally characterize neural circuitry in the fruit fly, Drosophila melanogaster, that …

Color vision extracts spectral information by comparing signals from photoreceptors with
different visual pigments. Such comparisons are encoded by color-opponent neurons that …

Background Linearly polarized light originates from atmospheric scattering or surface
reflections and is perceived by insects, spiders, cephalopods, crustaceans, and some …

Color vision is an important sensory capability of humans and many animals. It relies on
color opponent processing in visual circuits that gradually compare the signals of …

In Drosophila, color vision and wavelength‐selective behaviors are mediated by the
compound eye's narrow‐spectrum photoreceptors R7 and R8 and their downstream …
