In this paper, we address the role of proneural genes in the formation of the dorsal organ in the Drosophila larva. This organ is an intricate compound comprising the multineuronal dome—the exclusive larval olfactory organ—and a number of mostly gustatory sensilla. We first determine the numbers of neurons and of the different types of accessory cells in the dorsal organ. From...

Tracing of olfactory projections based on odorant receptor expression has led to an almost complete receptor-to-glomerulus map in adult Drosophila. While most of the glomeruli may be involved in processing of food odors, others appear to be more specialized, for example, responding to CO₂ or to pheromonal cues. Recent studies have shed light on signal processing in the antennal lobe and in...
