title: Three-dimensional antennal lobe atlas of the male moth, Agrotis ipsilon: a tool to study structure-function correlation.
abstract: The glomerular structure of the primary olfactory neuropil has long been thought to play an important role in odour coding. In insects, the number of glomeruli in the antennal lobe is limited in most species to fewer than 100 compared with more than 1,000 in vertebrates, making it possible to identify individual glomeruli. A complete three-dimensional atlas of the glomeruli within the antennal lobe of the male noctuid moth Agrotis ipsilon was constructed. All 66 glomeruli were singly identifiable in both antennal lobes of the three brains investigated. Further, six antennal lobes containing intracellularly stained projection neurones were reconstructed. By using the atlas, the respective target glomerulus of each projection neurone could be identified. The importance of the glomerular atlas as a tool to study central olfactory processing and its plasticity is discussed.
