1st part of a dorsal to ventral series of vibratome sections (100 μm) triple labeled for the nuclear marker (NUC; blue), synapsin immunoreactivity (SYN; red) and allatostatin-like immunoreactivity (AST; green) (A and C) and series of silver impregnated microtome sections (10 μm) (B and D). A to D: Photomontages of 2 × 3 pictures per slice. Corresponding pictures of equivalent horizons are shown in A and B and further ventrally C and D. Roman numeral VI identifies unstructured neuropil; Numbers 6, 10 and 9/11 identify cell clusters. Other abbreviations: AIINv, antenna II nerve; AnN, antenna II neuropil; CA, cerebral artery; CN, columnar neuropil, HN, hemiellipsoid neuropil; ICh, inner optic chiasm; La, lamina; Lo, lobula; LoP, lobula plate; M, medulla; mPC, medial protocerebrum; OC, oesophageal connective; OCh, outer optic chiasm; ON, olfactory neuropil (olfactory lobe); OT, optic tract; PB, protocerebral bridge; pF, posterior foramen; PT, protocerebral tract; TM, terminal medulla; TNv tegumentary nerve. Scale bar = 500 μm.
