Expression pattern of the membrane-trafficking molecule synaptotagmin-1 Dg-syt in adult females of Dinophilus gyrociliatus. The expression pattern is shown in ventral (a, c) and lateral (ventral side to the left, b) views as well as in a schematic drawing in ventral view (d). Dg-syt labels all perikarya of the brain, thereby resembling the pattern of Dg-six3/6, and can be furthermore shown around the mouth opening and—in approximately 20 % of animals—also labels the ganglionic accumulations in the anterior region of the ventral nerve cord. acom14 anterior commissure of segment 1–4, br brain, cb16 ciliary band 1–6, com13 commissural set of segment 1–3, fg frontal gland, lpmn lateral paramedian nerve, mcom14 median commissure of segment 1–4, mo mouth opening, mpmn median paramedian nerve, mvn medioventral nerve, np neuropil, pcom14 posterior commissure of segment 1–4, phb pharyngeal bulb, stnr stomatogastric nerve ring, vlnc ventrolateral nerve cord
