Motion-sensitive neurons have long been studied in both the mammalian retina and the
insect optic lobe, yet striking similarities have become obvious only recently. Detailed …

Detecting the direction of image motion is a fundamental component of visual computation,
essential for survival of the animal. However, at the level of individual photoreceptors, the …

Nonlinear, multiplication-like operations carried out by individual nerve cells greatly
enhance the computational power of a neural system,–, but our understanding of their …

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 …

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 …

Glutamatergic neurons are abundant in the Drosophila central nervous system, but their
physiological effects are largely unknown. In this study, we investigated the effects of …
