1The terminology used for cell groups is the same as in Sinakevitch et al. (2005). 2The approximate sizes of cell bodies are shown in parenthesis in μm. 3Total number of cell bodies on midline of SEG. NCC, nervii corpora cardiacii; FB, fan-shaped body; EB, ellipsoid body; PB, protocerebral bridge; D, L, M, or V Pro, dorsal, lateral, medial, or ventral protocerebrum; Ant Lo, antennal lobe; Op Lo; SEG, subesophageal ganglion; Trito, tritocerebrum, Deu, deutocerebrum (other than Ant Lo and Ant Mech); Ant Mech, antennal mechanosensory neuropil; sub CB, neuropil beneath ellipsoid and fan-shaped body; circum Ped, protocerebral neuropil surrounding pedunculus and vertical lobe (V Lo); α and γ division of mushroom body vertical lobe; L Ho, lateral horn of protocereberum; Ca, calyx; Oc N, ocellar nerve.
