Dorsal view of the head of a WT Molgula occidentalis mid tailbud embryo probed for Vsx (green) and Dmbx (magenta) expressions. Vsx is expressed in A11.119 and A11.117 cell pairs (respectively interneuron 1 precursor and interneuron 2).
Anterior is to the left. Boxed area is enlarged in insert.

Lateral view of a WT Molgula occidentalis mid tailbud embryo probed for Vsx (green) and Dmbx (magenta) expressions. Dmbx is expressed in A11.120 cell pair (anterior part of the visceral ganglion).
Original annotation : This double in situ shows expression of Dmbx in A11.120 (like Pax3/7). This is different from the situation in Ciona, in which Dmbx is detected only later, in the descending decussating neuron (ddN, equivalent to A12.239, the posterior daughter cell of A11.120).
Anterior is to the left. Boxed area is enlarged in insert.
