Type: Interneuron
Connectivity:
- In MoW: AVH
- In WormWiring:
AVHLh,
AVHRh,
AVHLm,
AVHRm
- In Nemanode: AVH
In Wormbase: AVH, AVHL, AVHR
Lineage: AB alapaaaaa, AB alappapaa
Location: Lateral ganglia of head
Description: Unipolar ventral cord interneurons. The processes of each AVH neuron enter the nerve ring and cross the midline into the contralateral side. The processes then exit the nerve ring into the ventral cord where they extend to the preanal ganglion.
Neurotransmitter/ Neuropeptide:
Innexin expression:
- INX-1a
- INX-10a
- INX-12 (in early larva)
- UNC-9 (only in dauer)
(Altun et al., 2009; Bhattacharya et al., 2019)
Receptor expression:
- GLR-4; glutamate receptor subunit
- SER-2; tyramine receptor (a splice variant)
- Possibly GGR-1; GABA-A/glycine receptor-like protein
(Tsalik et al., 2003; Brockie et al., 2001; Fujiwara et al., 1996)
Function:
- Regulates touch-evoked escape response and motility (Chai et al., 2022)
