The Mind of

Members: AIAL, AIAR.

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. Magnifications: (a, d) x 25500, (b, c) x 12750.
