初级嗅神经束的肾小球结构一直被认为在气味编码中起着重要作用。在昆虫中，触角叶中的小球数量在大多数物种中被限制在100个以下，而在脊椎动物中，小球的数量超过1000个，这使得识别单个小球成为可能。建立了一套完整的夜蛾触角叶内肾小球的三维图谱。所有66个肾小球在被调查的三个大脑的两个触角叶中都可以单独识别。此外，还重建了含有细胞内着色投射神经元的6个触角叶。通过使用图谱，可以识别每个投射神经元各自的靶球。讨论了肾小球图谱作为研究中枢嗅觉加工及其可塑性的工具的重要性。(C)2004年Wiley-Liss公司
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. (C) 2004 Wiley-Liss, Inc.
