Color and motion are used by many species to identify salient objects. They are processed
largely independently, but color contributes to motion processing in humans, for example …

Color and motion information are thought to be channeled through separate neural
pathways, but it remains unclear whether and how these pathways interact to improve …

In the visual system, peripheral processing circuits are often tuned to specific stimulus
features. How this selectivity arises and how these circuits are organized to inform specific …

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 …

Detecting the orientation and movement of edges in a scene is critical to visually guided
behaviors of many animals. What are the circuit algorithms that allow the brain to extract …

Whether motion vision uses color contrast is a controversial issue that has been investigated
in several species, from insects to humans. We used Drosophila to answer this question …

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 …

Detecting the direction of motion contained in the visual scene is crucial for many behaviors.
However, because single photoreceptors only signal local luminance changes, motion …

The reliable estimation of motion across varied surroundings represents a survival-critical
task for sighted animals. How neural circuits have adapted to the particular demands of …

The algorithms and neural circuits that process spatio-temporal changes in luminance to
extract visual motion cues have been the focus of intense research. An influential model, the …
