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

The visual ecology of flies is outstanding among insects due to a combination of specific
attributes. Flies' compound eyes possess an open rhabdom and thus separate rhabdomeres …

Whereas progress has been made in the identification of neural signals related to rapid,
cued decisions,–, less is known about how brains guide and terminate more ethologically …

Optogenetics allows the manipulation of neural activity in freely moving animals with
millisecond precision, but its application in Drosophila melanogaster has been limited. Here …

Color vision extracts spectral information by comparing signals from photoreceptors with
different visual pigments. Such comparisons are encoded by color-opponent neurons that …

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 vision is an important sensory capability that enhances the detection of contrast in
retinal images. Monochromatic animals exclusively detect temporal and spatial changes in …

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 …

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 …

Light sources attract nocturnal flying insects, but some lamps attract more insects than
others. The relation between the properties of a light source and the number of attracted …
