The retinal mosaics of many insects contain different ommatidial subtypes harboring
photoreceptors that are both molecularly and morphologically specialized for comparing …

Specialized ommatidia harboring polarization-sensitive photoreceptors exist in the 'dorsal
rim area'(DRA) of virtually all insects. Although downstream elements have been described …

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

In the fly optic lobe,∼ 800 highly stereotypical columnar microcircuits are arranged
retinotopically to process visual information. Differences in cellular composition and synaptic …

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 …

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

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 …

Drosophila vision is mediated by inputs from three types of photoreceptor neurons; R1–R6
mediate achromatic motion detection, while R7 and R8 constitute two chromatic channels …

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

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 …
