The medial protocerebrum and the olfactory globular tract. A and B: 3-D reconstruction protocerebral, deutocerebral neuropils and the olfactory globular tract in different orientation (see boxed figures). In A and B the cell cluster 6, the MAN, the OGT and the mPC fused with the CN are shown semitransparently, to make to visualize the subjacent structures. C and D: Horizontal vibratome section triple labeled against cell nuclei (NUC; blue), synapsin (SYN; red) and allatostatin-like (AST; green) immunoreactivity. In C, the negative print of the OGT is encircled by an interrupted line. E: A silver impregnation of a microtome slice is shown in a similar section plane. Arrowheads mark several neurons with strong ASTir. Numbers 6, 9/11 and 12 identify cell clusters. Other abbreviations: AcN, accessory neuropil; AMPN, anterior medial protocerebral neuropil; CA, cerebral artery; CB, central body neuropil; iT, interconnecting tract; LAN, lateral antenna I neuropil; MAN, median antenna I neuropil; mF, median foramen; OGT, olfactory globular tract, OGTN, OGT neuropil; OGTNa, accessory OGT neuropils; ON, olfactory neuropil; PB, protocerebral bridge neuropil; PMPN, posterior medial protocerebral neuropil.
