FIGURE 2

(A) Larval sensory neurons in Ciona robusta (see Ryan et al., 2017). Left lateral view. In the tail there are two groups of caudal epidermal neurons, 12 dorsal (DCENs) and 12 ventral (VCENs). There are three groups of Trunk Epidermal Neurons, 12 rostral (RTEN), four anterior (aATENs) and four posterior (pATENs). There are three rostral papillae with two pairs of sensory neurons (Pns) each. (B,C) frontal and cross sections of C. robusta, showing some sensory structures: the anterior dorsal papilla (P), and the sensory vesicle (SV) with the otolith and the ocellus, Toluidine blue. C1-C2: tunic cuticular layer; EC: endodermal cavity; LB: larval brain; MG: motor ganglion; NC: nerve cord; NT: notochord; SV: sensory vesicle.
