Scutigeromorpha. A Scutigera coleoptrata. B Single optical section of a neurobiotin backfill showing an olfactory lobe with distinct olfactory glomeruli. cLSM scan. C cLSM scan (maximal projection) of the brain and the subesophageal ganglion. View from ventral. Left antennal nerve was filled with neurobiotin. Antennal neurites project into the seg. D 3D reconstruction of the brain of S. coleoptrata with deutocerebral neuropils. Blue: olfactory glomeruli, yellow: corpus lamellosum. Abbreviations: cl corpus lamellosum, clc contralateral connection, fg frontal ganglion, na nervus antennalis, np neurite projections, ol olfactory lobe, pc protocerebrum, seg subesophageal ganglion.
