AVG
The Mind of 
	a Worm

Member: AVG.

AVG is a single interneuron with its cell body situated in the retro-vesicular ganglion. A posteriorly directed, fairly large process leaves the cell body and runs in the dorsal region of the cord down to the pre-anal ganglion. Here it runs to the left of the anus and enters the dorso-rectal ganglion and from there runs down the dorsal hypodermal ridge to the tip of the tail. The disposition of the posterior extremities of this process suggest that it could be a sensory dendrite. There are a few scattered synapses in the ventral cord (e.g. d) the most prominent of which are some synapses to AVB (a). There are several synapses onto the basal lamina surrounding the nerve cord with no obvious postsynaptic partners (c). The most striking features of AVG are the gap junctions it makes with RIF in the retro-vesicular ganglion (b). A short anteriorly directed process from AVG often pokes into the cell bodies of one of the RIF neurons (b). Magnifications: (a) x 25500, (b-d) x 17000.
