AWB
The Mind of 
	a Worm

Members: AWBL, AWBR.

AWB is a set of two ciliated neurons with flattened, sheet-like endings that are associated with the sheath cells of the amphid sensilla (figure 1). Cell bodies are situated in the lateral ganglion and send processes into the ventral cord via the amphid commissures. The processes run anteriorly in the ventral part of the nerve cord and project into the nerve ring, where they run near the middle of the neuropile. They meet and stop at the dorsal mid-line with a gap junction. The processes are fairly small and none of the synapses is very large. The main synaptic output is to AIZ and ADF, usually together in a dyadic synapse (a). There are also synapses to RIA (b) and AVB (c). There are gap junctions to RMG (d) and AUA.
