Schematic drawing of the brain of B. latro (dorsal view), idealized from ca. 40 horizontal silver-stained sections (10 μm) and several immunostained sections of (100 μm) of four animals. Abbreviations: arrows: deutocerebral organ; 5, 6, 9, 10 identify cell clusters; AINv, antenna I nerve; AIINv, antenna II nerve; AcN, accessory neuropil; AMPN, anterior medial protocerebral neuropil; AnN, antenna II neuropil; CA, cerebral artery; CB, central body neuropil; CN, columnar neuropil; Me, medulla (external medulla); HN, hemiellipsoid neuropil; ICh, inner chiasma; La, lamina; LAN, lateral antenna I neuropil; Lo, lobula (internal medulla); LoP, lobula plate; MAN, median antenna I neuropil; OC, oesophageal connective; OCh, outer chiasma; OGT, olfactory globular tract; OGTN, olfactory globular tract neuropil; ONa, ONd and ONp, anterior, dorsal and posterior sublobe of the olfactory neuropil ON (shown at the left hemisphere of the brain, more detailed with columnar olfactory glomeruli); ONv, optic nerve; OT, optic tract; PB, protocerebral bridge; PMPN, posterior medial protocerebral neuropil; PT, protocerebral tract; TM, terminal medulla (medulla terminalis); TNv, tegumentary nerve.
