The deutocerebral olfactory neuropil. A to C: 3D-reconstruction of the olfactory and accessory neuropil in different orientations. In A, the cell clusters are shown semitranparently to visualize the subjacent structures. D to F: Horizontal vibratome section double or triple labeled against cell nuclei (NUC; blue), synapsin (SYN; red) and allatostatin-like (AST; green) immunoreactivity in higher magnification from Fig. 4C. The three subdivided regions of the glomeruli are shown in F (higher magnificated from Fig. 5C), marked with Cap, Subcap and Base. Note that in G, the horizontal vibratome section with immunohistochemical labeling against SIFamide (SIF; black) is obtained from another animal, but in a similar section plane like F. Roman numeral IV identifies an unstructured neuropil within the olfactory neuropil (ON). Numbers 9 to 11 identify cell clusters. Other abbreviations: AcN, accessory neuropil; AMPN, anterior medial protocerebral neuropil; mF, median foramen; DO, deutocerebral organ; OGTN(a), (accessory) olfactory globular tract neuropil; ONa, anterior; ONd, dorsal and ONp, posterior sublobes of the olfactory neuropil; pF, posterior foramen; PMPN, posterior medial protocerebral neuropil.
