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

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

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 …

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) …

The Drosophila larva modulates its pattern of locomotion when exposed to light. Modulation
of locomotion can be measured as a reduction in the distance traveled and by a sharp …

The ability to sense and to react to environmental stimuli is crucial for the survival of any
organism. The primary event in sensory information processing is the transduction of …

Visual systems extract multiple features from a scene using parallel neural circuits.
Ultimately, the separate neural signals must come together to coherently influence action …

Sensory systems sequentially extract increasingly complex features. ON and OFF pathways,
for example, encode increases or decreases of a stimulus from a common input. This …

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 …

How neurons detect the direction of motion is a prime example of neural computation:
Motion vision is found in the visual systems of virtually all sighted animals, it is important for …
