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. acom1–4 anterior commissure of segment 1–4, br brain, cb1–6 ciliary band 1–6, com1–3 commissural set of segment 1–3, fg frontal gland, lpmn lateral paramedian nerve, mcom1–4 median commissure of segment 1–4, mo mouth opening, mpmn median paramedian nerve, mvn medioventral nerve, np neuropil, pcom1–4 posterior commissure of segment 1–4, phb pharyngeal bulb, stnr stomatogastric nerve ring, vlnc ventrolateral nerve cord
