Drosophila R7 UV photoreceptors (PRs) are divided into yellow (y) and pale (p) subtypes.
yR7 PRs express the Dpr11 cell surface protein and are presynaptic to Dm8 amacrine …

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 …

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 …

Many visual animals have innate preferences for particular wavelengths of light, which can
be modified by learning. Drosophila's preference for UV over visible light requires UV …

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

Color vision in Drosophila relies on the comparison between two color-sensitive
photoreceptors, R7 and R8. Two types of ommatidia in which R7 and R8 contain different …

The Drosophila visual system consists of the compound eyes and the optic ganglia in the
brain. Among the eight photoreceptor (R) neurons, axons from the R1-R6 neurons stop …

The receptor mechanism for color vision has been extensively studied. In contrast, the circuit
(s) that transform (s) photoreceptor signals into color percepts to guide behavior remain (s) …

INTRODUCTION Neuronal fate decisions must be coordinated across brain regions so that
the proper stoichiometry of distinct afferents and their target neurons is established. Many …

Color discrimination requires the input of different photoreceptor cells that are sensitive to
different wavelengths of light. The Drosophila visual system contains multiple classes of …
