This review surveys the organization of the olfactory and gustatory systems in the imago and in the larva of Drosophila melanogaster, both at the sensory and the central level. Olfactory epithelia of the adult are located primarily on the third antennal segment (funiculus) and on the maxillary palps. About 200 basiconic (BS), 150 trichoid (TS) and 60 coeloconic sensilla (CS) cover the surface of the funiculus, and an additional 60 BS are located on the maxillary palps. Males possess about 30… Expand
The larval chemosensory system of Drosophila melanogaster : neuroanatomy and neurotransmitter distribution
We provide a detailed analysis of the larval head chemosensory system of Drosophila melanogaster, based on confocal microscopy of cell-specific reporter gene expression in P[GAL4] enhancer trapExpand
Neuroethology of the Olfactory System of Drosophila-Evolution and Specialization
In insects olfaction is a primary sensory modality. As a result changes in the animal’s ecology are often paralleled by modifications in the olfactory system. Using a comparative approach between theExpand
Adult‐like complexity of the larval antennal lobe of D. melanogaster despite markedly low numbers of odorant receptor neurons
TLDR
The largely reduced numbers of afferents and the similar architecture of the LAL and the adult antennal lobe render the larval chemosensory system of Drosophila a valuable model system, both for studying smell and taste and for examining the development of its adult organization. Expand

TLDR
The results suggest that pit, papilla and knob sensilla act in contact chemosensation, however, they likely do these employing different stimulus transduction mechanisms to sense the diverse chemicals of their environment. Expand
A Neuronal Network Model of Drosophila Antennal Lobe
TLDR
A conductance based neuronal network model of the Drosophila antennal lobe is constructed with the aim of understanding possible mechanisms within the antennale lobe that account for the variety of projection neuron activity observed in experimental data. Expand
Neuroethology of Olfaction in Drosophila
TLDR
This work demonstrates how the olfactory system of adults of specialist fruitfly Drosophila sechellia has evolved to accommodate its unique preference for Morinda citrifolia fruit and investigates the significance of three new ligands biologically active for coeloconic neurons in odor coding and in fly attraction. Expand
Architecture of the primary taste center of Drosophila melanogaster larvae
TLDR
This work provides a description of the primary taste center in the larval central nervous system of Drosophila larvae and suggests a subtle functional organization: aversive and attractive stimuli might be processed in the anterior and posterior part of the SOG, respectively. Expand
Fine structure and primary sensory projections of sensilla located in the sacculus of the antenna of Drosophila melanogaster
TLDR
The sacculus in Drosophila has sensilla that are predominantly involved in hygroreception, thermoreception, and olfaction, and the sensory projections of the neurons innervating the sacculus sensilla of chamber III are traced. Expand
Central projections of olfactory receptor neurons from single antennal and palpal sensilla in mosquitoes.
TLDR
This work has developed a method to stain central projections of intact receptor neurons known to respond to host odor compounds in the malaria mosquito, Anopheles gambiae, and revealed unilateral arborizations in an area at a similar position as in An. Expand
Function and central projections of gustatory receptor neurons on the antenna of the noctuid moth Spodoptera littoralis
TLDR
Responses of individual taste sensilla on the antennae of Spodoptera littoralis to sugars and salts were measured using tip recordings and the projections of their neuronal axons into the brain were traced. Expand

Fine structure and primary sensory projections of sensilla on the maxillary palp of Drosophila melanogaster Meigen (Diptera : Drosophilidae)
TLDR
The fibres from a sensillum project to the brain with respect to their functions and the individual glomeruli represent functional units of the brain, receiving inputs in a characteristic combination. Expand
Neuronal architecture of the antennal lobe in Drosophila melanogaster
TLDR
Computer reconstruction of the antennal lobe of Drosophila melanogaster has revealed a total of 35 glomeruli, of which 30 are located in the periphery of the lobe and 5 in its center, and no obvious sexual dimorphism of the glomerular architecture was observed. Expand
Olfactory Bulb and Antennal Lobe
TLDR
Each of these centres is the first central station in the olfactory pathway of animals on a par with one another in their ability to detect, discriminate and identify even complex scents, and with equivalent skills in locating and seeking out odour sources and in learning odours. Expand
An accessory olfactory pathway in Lepidoptera: the labial pit organ and its central projections in Manduca sexta and certain other sphinx moths and silk moths
TLDR
It is suggested that the labial pit organ in the hawkmoth, Manduca sexta, serves as an accessory olfactory organ in adult Lepidoptera. Expand
Projection patterns of different types of antennal sensilla in the antennal glomeruli of Drosophila melanogaster
SummaryCobalt fills from small, defined regions of the antenna in D. melanogaster show that the three types of sensilla on the third segment, the flagellum, and a fourth sensillum located in theExpand
Anatomical and neurochemical classification of the antennal glomeruli in Drosophila melanogaster meigen (Diptera : Drosophilidae)
TLDR
Toluidine-methylene blue staining has revealed the presence of 22 glomeruli in the antennal lobe of Drosophila melanogaster, and 15 of them demonstrated specific uptake of choline, which is suggestive of some cholinergic innervation. Expand
Projections of leg proprioceptors within the CNS of the fly Phormia in relation to the generalized insect ganglion
TLDR
An atlas of the fly CNS is provided and the locust is compared with the model for much insect neuroanatomy and neurophysiology to apply the results of this study to a broader range of insects. Expand
Peripheral and central nervous effects of lozenge3: a Drosophila mutant lacking basiconic antennal sensilla.
TLDR
Mosaic flies exhibiting a lozenge3 antenna demonstrate that the elimination of glomerulus V is causally related to the change in the sensilla pattern, which implies that the development and/or survival of particular target regions in the antennal center depends on sensory input. Expand
Analysis of immunocytochemical staining patterns in the antennal system of Drosophila melanogaster
TLDR
Six monoclonal antibodies that bind to the olfactory system of Drosophila with various degrees of specificity are obtained and staining patterns include sheath cells of basiconic and coeloconic sensilla. Expand

TLDR
The columnar organization of the system is emphasized, alternative models of antennal-neuron projection into glomeruli are considered, and the functional significance of identifiedglomeruli is discussed. Expand
