Type: Interneuron
In MoW: AVD
Male Wiring Project: AVDL, AVDR
In Wormbase: AVD, AVDL, AVDR
Lineage: AB alaaapalr, AB alaaapprl
Location: Lateral ganglia of head
Description: 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. (VA, DA) and AS motor neurons. Formerly called delta.
Neurotransmitter:
Function: 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 et al., 1995; Brockie et al., 2001). Express UNC-8, a DEG/ENaC family member homologous to subunits of a candidate mechanically gated ion channel (Tavernarakis et al., 1997).
