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 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 eye, visual information is segregated into modalities such as color and motion, these
being transferred to the central brain through separate channels. Here, we genetically …

Visual systems extract directional motion information from spatiotemporal luminance
changes on the retina. An algorithmic model, the Reichardt detector, accounts for this by …

The visual systems of most species contain photoreceptors with distinct spectral sensitivities
that allow animals to distinguish lights by their spectral composition. In Drosophila …

In the visual system of Drosophila, photoreceptors R1–R6 relay achromatic brightness
information to five parallel pathways. Two of them, the lamina monopolar cells L1 and L2 …

Recent experiments have shown that motion detection in Drosophila starts with splitting the
visual input into two parallel channels encoding brightness increments (ON) or decrements …

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 …

Whether fundamental visual attributes, such as color, motion, and shape, are analyzed
separately in specialized pathways has been one of the central questions of visual …

Inhibitory interactions between opponent neuronal pathways constitute a common circuit
motif across brain areas and species. However, in most cases, synaptic wiring and …
