|Lateral ganglia of head||
One of four bilaterally symmetric interneuron pairs (AVA, AVB, AVD, and PVC) with large-diameter axons that run the entire length of the ventral nerve cord and provide input to the ventral cord motor neurons.Synapse onto A-type (VA, DA) and AS motor neurons. Formerly called delta .
Functions: Command interneuron. Functions as touch modulator for backward locomotion induced by head-touch. Drives backward movement of the animal along with driver cell AVA neuron, AVE and A-type motor neurons. See Locomotory circuit.
Receptor expression: Express glutamate receptor subunits, GLR-1 , GLR-2, GLR-5, NMR-1 and NMR-2 (Maricq A. V. et al 1995)(Brockie P.J. et al 2001). Express UNC-8, a DEG/ENaC family member homologous to subunits of a candidate mechanically gated ion channel (Tavernarakis N. et al, 1997).
