A good starting reference would be M. Chalfie and J. White's
chapter in _The Nematode Caenorhabditis elegans_, W.B. Wood (ed.),
1988, Cold Spring Harbor Laboratory Press.
It's thought that excitatory body-wall muscle motor neurons
use acetylcholine. Inhibitory motor neurons use GABA.
Excitatory motor neurons in the egg-laying circuitry seem
to be using serotonin.
Dopamine and octopamine have been detected in the worm as
well.
