Organisation of the central nervous system of E. rowelli. 3D renderings based on SRμCT (a, b) and Azan staining (c, d). Dorsal is up in all images. a Overview. b Detail of suprarectal commissure. Asterisk indicates passage of genital duct under ventral nerve cord. c, d Frontal and lateral views of anterior part of nervous system. Cell body rind (blue) partly covers neuropils, fibre tracts, commissures and peripheral nerves (light-brown). c', c” Selected frontal slices from (c) at the level of the brain (c') and ventral nerve cord (c”). ANC, antennal nerve cord; BR, brain; CNC, circumpharyngeal nerve cord; DC, dorsal commissures; EY, eye; HO, hypocerebral organ; JAN, jaw nerve; LEN, leg nerve; LE, leg; LIN 1, LIN 2, lip nerve1 and 2; PHN 1, pharyngeal nerve 1; SP, slime papilla; SPN, slime papilla nerves; SRC, suprarectal commissure; VC, ventral commissure; VNC, ventral nerve cord
