Members: DVC.
DVC is a single interneuron with its cell body situated in the dorso-rectal ganglion. An
anteriorly directed process enters the ventral cord and runs in the dorsal part of the process
bundle until the nerve ring is reached. It enters the nerve ring close to the ventral mid-line
and then runs right round it in a clockwise direction on the outside surface of the neuropile.
At all times along its length, the process of DVC runs in close association with that of DVB.
In the nerve ring the main synaptic output is to RIG (a, b), AVA (c), AIB (c) and RMF (b),
and there are gap junctions to AIB. In the ventral cord there is some synaptic input from DVB and there are also many gap junctions to PVP (d) and several rather marginal gap junctions
to AVL and VD1.
