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

Motion vision provides essential cues for navigation and course control as well as for mate,
prey, or predator detection. Consequently, neurons responding to visual motion in a …

Animal behaviour arises from computations in neuronal circuits, but our understanding of
these computations has been frustrated by the lack of detailed synaptic connection maps, or …

A mechanistic understanding of neural computation requires determining how information is
processed as it passes through neurons and across synapses. However, it has been …

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 …

Monitoring voltage dynamics in defined neurons deep in the brain is critical for unraveling
the function of neuronal circuits but is challenging due to the limited performance of existing …

In dynamic environments, animals make behavioural decisions on the basis of the innate
valences of sensory cues and information learnt about these cues across multiple …

Analysing computations in neural circuits often uses simplified models because the actual
neuronal implementation is not known. For example, a problem in vision, how the eye …

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 …

The perception of visual motion is critical for animal navigation, and flies are a prominent
model system for exploring this neural computation. In Drosophila, the T4 cells of the …
