Organization of the Drosophila larval visual circuit.

摘要: Visual systems transduce, process and transmit light-dependent environmental cues. Computation of visual features depends on photoreceptor neuron types (PR) present, organization the eye wiring underlying neural circuit. Here, we describe circuit architecture system Drosophila larvae by mapping synaptic diagram neurotransmitters. By contacting different targets, two larval PR-subtypes create converging pathways potentially computation ambient light intensity temporal changes already within this first processing center. Locally processed information then signals via dedicated projection interneurons to higher brain areas including lateral horn mushroom body. The stratified structure optic neuropil (LON) suggests common organizational principles with adult fly vertebrate systems. complete LON paves way understanding how circuits reduced numerical complexity control wide ranges behaviors.
