The importance of retinal innervation for the normal development of the optic ganglia in
Drosophila is well documented. However, little is known about retrograde effects of the optic …

Background Color vision requires comparison between photoreceptors that are sensitive to
different wavelengths of light. In Drosophila, this is achieved by the inner photoreceptors (R7 …

Sensory systems provide abundant information about the environment surrounding an
animal, but only a small fraction of that information is relevant for any given task. One …

We reconstructed the synaptic circuits of seven columns in the second neuropil or medulla
behind the fly's compound eye. These neurons embody some of the most stereotyped …

Visual systems transduce, process and transmit light-dependent environmental cues.
Computation of visual features depends on photoreceptor neuron types (PR) present …

The brain's synaptic networks endow an animal with powerfully adaptive biological
behavior. Maps of such synaptic circuits densely reconstructed in those model brains that …

At the layer of first visual synapses, information from photoreceptors is processed and
transmitted towards the brain. In fly compound eye, output from photoreceptors (R1–R6) that …

Although glial cells have been implicated widely in the formation of axon tracts in both
insects and vertebrates, their specific function appears to be context-dependent, ranging …

The ability of vertebrates and insects to perceive and process information about the visual
world is mediated by neural circuits, which share a strikingly conserved architecture of …

Mutations at the X-linked disconnected locus of D. melanogaster lead to the failure of adult
photoreceptor axons to innervate their target cells in the developing optic lobes of the third …
