Many of the subtleties in the evolutionary tuning of sensory systems still escape us. Insect
color vision is a typical case. While we know much about its mechanisms, the abundant …

It is a commonly held misconception that dogs are color blind. The truth is that a dog's ability
to see colors is similar to that of most other mammals, 1 although different from that of …

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 …

Drosophila melanogaster has long been a popular model insect species, due in large part to
the availability of genetic tools and is fast becoming the model for insect colour vision. Key to …

Colour vision allows animals to use the information contained in the spectrum of light to
control important behavioural decisions such as selection of habitats, food or mates. Among …

Today, there is good knowledge of the physiological basis of bird colour vision and how
mathematical models can be used to predict visual thresholds. However, we still know only …

Animals navigating in natural environments must handle vast changes in their sensory input.
Visual systems, for example, handle changes in luminance at many timescales, from slow …

Many animals use the spectral distribution of light to guide behaviour, but whether they have
colour vision has been debated for over a century. Our strong subjective experience of …

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

Colour discrimination is based on opponent photoreceptor interactions, and limited by
receptor noise. In dim light, photon shot noise impairs colour vision, and in vertebrates, the …
