Background Color vision is commonly assumed to rely on photoreceptors tuned to narrow
spectral ranges. In the ommatidium of Drosophila, the four types of so-called inner …

Originally a genetic model organism, the experimental use of Drosophila melanogaster has
grown to include quantitative behavioral analyses, sophisticated perturbations of neuronal …

Background In the fly's visual motion pathways, two cell types—T4 and T5—are the first
known relay neurons to signal small-field direction-selective motion responses [1]. These …

Temporal patterning of neural progenitors is one of the core mechanisms generating
neuronal diversity in the central nervous system. Here, we show that, in the tips of the outer …

Highlights•We describe recent advances in the field of visual processing in Drosophila.•We
present in detail the neuronal circuits underlying four visual modalities.•Motion vision …

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

Genetic screens in Drosophila have identified many genes involved in neural development
and function. However, until recently, it has been impossible to monitor neural signals in …

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 …

How stem cells produce the huge diversity of neurons that form the visual system, and how
these cells are assembled in neural circuits are a critical question in developmental …

Many visual animals have innate preferences for particular wavelengths of light, which can
be modified by learning. Drosophila's preference for UV over visible light requires UV …
