Whereas the “vertical” elements of the insect olfactory pathway, the olfactory receptor neurons and the projection neurons, have been studied in great detail, local interneurons providing “horizontal” connections in the antennal lobe were ignored for a long time. Recent studies in adult Drosophila demonstrate diverse roles for these neurons in the integration of odor information,...

Odor discrimination in higher brain centers is essential for behavioral responses to odors. One such center is the mushroom body (MB) of insects, which is required for odor discrimination learning. The calyx of the MB receives olfactory input from projection neurons (PNs) that are targets of olfactory sensory neurons (OSNs) in the antennal lobe (AL). In the calyx, olfactory information is...

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...

Background: Drosophila larvae possess only 21 odorant-receptor neurons (ORNs), whereas adults have 1,300. Does this suggest that the larval olfactory system is built according to a different design than its adult counterpart, or is it just a miniature version thereof? Results: By genetically labeling single neurons with FLP-out and MARCM techniques, we...

The sense organs of adult Drosophila, and holometabolous insects in general, derive essentially from imaginal discs and hence are adult specific. Experimental evidence presented here, however, suggests a different developmental design for the three largely gustatory sense organs located along the pharynx. In a comprehensive cellular analysis, we show that the posteriormost of the three organs...
