AIA is a set of two interneurons with cell bodies situated in the
ventral ganglion. Their
processes run up the ventral cord, run round the nerve ring close to
the posterior face of the
neuropile and terminate at the dorsal mid-line with a gap junction to
their contralateral
partners (b). The processes of AIA run in close association with the
proximal regions of the
processes from AIB (a). AIA is one of the main classes of integrating
neuron for the neurons
of the amphid sensilla, receiving synaptic inputs predominantly from
ASK (*a), ASG (*a),
ASH (*a), ADL (*a), PVQ (*a-*d), AIM (*a), ASE (*b), AWC (*c), AIZ
and ASI (*a).
Most of these synapses are dyadic; AIB is the corecipient. The main
synaptic output is to AIB,
often as a dyadic with RIF (a) or AWC (b) as the corecipient. AIA has
gap junctions to ASI
(c), AWA (d) and ADF.
