Fig. 4 Z-projections of the details of the nervous system of Gnathostomula paradoxa visualized with CLSM. Tyrosinated tubulinlike immunoreactivity in yellow, cell nuclei visualized with DAPI in cyan, serotonin-like immunoreactivity in white (b, c) and red (d–f), Factin phalloidin staining in green, FMRF-amid-like immunoreactivity in glow (g) and magenta (h and i), synapsin 1-like immunoreactivity in blue. Anterior to the left. a Sensory structures in antero-lateral part of the rostrum. b Posterior end of animal, showing posterior commissure and tail innervation. c Posterior end of animal, details of dorsal structures. d Ventral nervous structures in pharyngeal region. e and f Ventral nervous structures in the middle part of the animal. g FMRF-amid-like immunoreactivity in the entire body, ventral view. h FMRF-amid-like
