Organisation and characterisation of brain neuropils in E. rowelli. Three-dimensional reconstruction based on anti-acetylated α-tubulin immunolabelling. a Brain in dorsal (left) and ventral views (right) illustrating largely fused neuropils and lobes (bluish grey). For clarity the mushroom bodies, olfactory lobes, frontal neuropil, visual pathways and central body are collectively shown in semi-transparent light grey. b Colour-coded brain areas in dorsal (left) and ventral views (right). c Same as b in anterolateral view. ANC, antennal nerve cord; ANP, antennal neuropil; CBR, cell body rind; CN, central neuropil; CNC, circumpharyngeal nerve cord; DN, deutocerebral neuropil; EY, eye; JAN, jaw nerve; LIN 2, LIN 3, lip nerves 2 and 3; ML, median lobe; ONP, optic neuropil; PHN 1, pharyngeal nerves 1; PDN, posterior dorsal neuropil; PVN, posterior ventral neuropil; SAN, subantennal neuropil; SPC, subpharyngeal commissure; SPN, slime papilla nerve; VH, ventral horn
