Confocal images and three-dimensional reconstructions of the antennal-lobe (AL) glomeruli in a frontal view.

A1–H1: confocal images of AL sections at different depths. The most anterior glomeruli, at 27 μm (A). 42 μm (B). 63 μm (C). 78 μm (D). 90 μm (E). 105μm (F). 123 μm (G). 138 μm (H). A2–H2: Same confocal images as shown in A1–H1, but with labeling. A3–H3: Three-dimensional reconstructions of glomeruli based on the confocal images shown in A2–H2 (frontal view). The stars indicate the antennal lobe hub. AN: antennal nerve; cLFG: central large female glomerulus; LAL: lateral accessory lobe; LCCl: lateral cell body cluster; BPL: bundle of primary neurites connected to the LCCl; MCCl: medial cell body cluster; BPM: bundle of primary neurites connected to the MCCl; PC: protocerebrum; VLP: ventro-lateral protocerebrum. Directions: A, anterior; D, dorsal; L, lateral; M, medial; P, posterior; V, ventral. Scale bars = 100 μm. The scale bar in H1 was also applied to A1–G1 and A2–H2, and in H3 applied to A3–G3.
