The Mind of

Members: AIZL, AIZR.

AIZ is a set of two interneurons with cell bodies situated in the lateral ganglia. AIZ is one of the main classes of integrating neuron for the receptors of the amphid sensilla. Processes enter the ventral cord via the amphid commissures and run anteriorly near the ventral surface of the neuropile. Most of the synaptic output is in the region of the neuropile of the ventral ganglion. The processes then enter the nerve ring and run round it in close association with the processes of ADF near the middle of the neuropile. They move slightly anteriorly on the dorsal side of the nerve ring and meet and terminate at the dorsal mid-line with a gap junction between them (b). The main synaptic outputs are to RIA (a, c, d), SMB (a, c, d), AIB (e, f, g), RIM (e, g), AIY (f) and AVE. The main synaptic inputs are from ADF (*a), AWA (*a), AIY (*a, *c, *e), RIR (*c), AWB (*a), RIH (*a) and HSN (*f). Gap junctions are made to ASH and ASG (h) near the amphid commissures. Magnifications: (a, h) x 25500, (b-g) x 12750.
