AWC
The Mind of 
	a Worm

Members: AWCL, AWCR.

AWC is a set of two ciliated neurons with large, flattened, sheet-like endings that are associated with the sheath cells of the amphid sensilla (figure 1). The cell bodies of AWC are situated in the lateral ganglia and send processes into the ventral cord via the amphid commissures. These turn anteriorly and run near the lateral surfaces of the cord. They then enter the nerve ring which they then run right round adjacent to the posterior surface; finally ending ventrally. The main synaptic output is to AIY (a), AIB (b) and AIA (c) which synapses back to AWC reciprocally (d). AWC also has some synaptic input from ASE (*d) and ASI (*c). Occasional dark vesicles are seen at synapses (a). Magnifications: (a) x 25500, (b-d) x 12750.
