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 …

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

Motion vision is a major function of all visual systems, yet the underlying neural mechanisms
and circuits are still elusive. In the lamina, the first optic neuropile of Drosophila …

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 …

The extraction of directional motion information from changing retinal images is one of the
earliest and most important processing steps in any visual system. In the fly optic lobe, two …

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 …

Visual motion perception is critical to many animal behaviors, and flies have emerged as a
powerful model system for exploring this fundamental neural computation. Although …

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 …

Across animal phyla, motion vision relies on neurons that respond preferentially to stimuli
moving in one, preferred direction over the opposite, null direction. In the elementary motion …

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 …
