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 …

Fly visual circuits are organized into lattice-like arrays and layers. Recent genetic studies
have provided insights into how these reiterated structures are assembled through stepwise …

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 …

Synaptic circuits for identified behaviors in the Drosophila brain have typically been
considered from either a developmental or functional perspective without reference to how …

The brain areas that endow insects with the ability to see consist of remarkably complex
neural circuits. Reiterated arrays of many diverse neuron subtypes are assembled into …

Like other sensory systems, the visual system is topographically organized: Its sensory
neurons, the photoreceptors, and their targets maintain point-to-point correspondence in …

Background Many animals extract specific cues from rich visual scenes to guide appropriate
behaviors. Such cues include visual motion signals produced both by self-movement and by …

Understanding how activity patterns in specific neural circuits coordinate an animal's
behavior remains a key area of neuroscience research. Genetic tools and a brain of …

The central complex is a highly conserved insect brain region composed of morphologically
stereotyped neurons that arborize in distinctively shaped substructures. The region is …

In both vertebrates and invertebrates, evidence supports separation of luminance
increments and decrements (ON and OFF channels) in early stages of visual processing (;); …
