3D-reconstruction from serial semithin sections; Zoea 1 of Hippolyte inermis (modified from [167]). a Six sections as examples from a series of transversal semithin section series. The dotted lines indicate the neuropil borders used for the 3D-reconstruction in b, and c). b 3D-reconstruction of median protocerebrum, visual neuropils and brain surface (transparent) in frontal view. c Central nervous system with neuromeres, surface (transparent), and segmental nerves. Surface renderings were made in Amira 5.2.0. Colours: transparent red—surface of protocerebrum, transparent green—surface of deutocerebrum and tritocerebrum, transparent blue—surface of suboesophageal and pereion ganglia, red—retina of compound eye, yellow—visual neuropils, orange—median protocerebral neuropils, light green—neuropils of deutocerebrum, dark green—neuropils of tritocerebrum, blue—neuropils of suboesophageal and pereion ganglia
