Fundamental to living cells is the capacity to differentiate into subtypes with specialized
attributes. Understanding the way cells acquire their fates is a major challenge in …

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

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 …

Airborne insects are miniature w ing-flapping aircraft the visually guided manoeuvres of
which depend on analogue,'fly-by-wire'controls. The front-end of their visuomotor system …

Drosophila colour vision is achieved by R7 and R8 photoreceptor cells present in every
ommatidium. The fly retina contains two types of ommatidia, called 'pale'and 'yellow', defined …

The Drosophila nlnaE gene was isolated by a multistep protocol on the basis of its homology
to bovine opsin cDNA. The gene encodes the maior visual pigment protein (opsln) …

Color discrimination requires the input of different photoreceptor cells that are sensitive to
different wavelengths of light. The Drosophila visual system contains multiple classes of …

Drosophila visual transduction is the fastest known G-protein-coupled signaling cascade
and has therefore served as a genetically tractable animal model for characterizing rapid …

▪ Abstract The Drosophila phototransduction cascade has emerged as an attractive
paradigm for understanding the molecular mechanisms underlying visual transduction, as …
