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) …

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 …

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 of humans and many animals. It relies on
color opponent processing in visual circuits that gradually compare the signals of …

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 …

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

In the perception of color, wavelengths of light reflected off objects are transformed into the
derived quantities of brightness, saturation and hue. Neurons responding selectively to hue …

Background Color vision is commonly assumed to rely on photoreceptors tuned to narrow
spectral ranges. In the ommatidium of Drosophila, the four types of so-called inner …

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