Comparison of individual commissures, tracts, lobes and neuropils in the brain of E. rowelli. Three-dimensional reconstructions in dorsal (left halves) and ventral views (right halves). Anterior is up in all images. Arrowheads indicate position of microglomeruli. BRC 1, BRC 2, BRC 3, brain commissure 1 to 3; FGC, fascicles of globuli cells; CB, central body; CBA, anterior division of central body; CB-AN, auxiliary neuropil of central body; CB-IL, inner lamina of central body; CB-OL, outer lamina of central body; CBP, posterior division of central body; CNC, circumpharyngeal nerve cord; E-ONP, extracerebral part of optic neuropil; FB, frontal body; I-ONP, intracerebral part of optic neuropil; λ, lateral or λ-lobe; LO, lobes of mushroom body; MG, macroglomerulus; μ, median or μ-lobe; ν, ventral or ν-lobe; OLF 1, OLF 2, OLF 3, OLF 4, olfactory fascicles 1 to 4; OLG, olfactory glomeruli; ONP, optic neuropil; PED, pedunculus; PNT, ponticulus
