General Information
Term adult feeding interneuron ID (Ontology) FBbt:00110985 (Fly Anatomy)
Definition Adult subesophageal zone intrinsic neuron whose soma is located in the lateral gnathal ganglion (Flood et al., 2013). The primary neurite extends ventromedially into the gnathal ganglion and splits into several dendritic branches that form a dense network of arborization medial to the axonal arbors (Flood et al., 2013). This arborization is predominantly ipsilateral, but dendrites may spread into the contralateral hemisphere (Flood et al., 2013). It is involved in inducing the proboscis extension reflex and might also be involved in regulating consumption (Flood et al., 2013; Pool et al., 2014; Shiu et al., 2022). There is one of these neurons in each hemisphere (Flood et al., 2013). It is predicted to be cholinergic (Shiu et al., 2022). It is predicted to be a primary neuron (Dorkenwald et al., 2024; Schlegel et al., 2024).[ FlyBase:FBrf0222061 FlyBase:FBrf0225542 FlyBase:FBrf0251280 FlyBase:FBrf0254006 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0260565 ]
Also Known As"adult CB0038 neuron" ; "CB0038" ; "Fdg" (for all, see Synonyms field below)
CommentNeurotransmitter prediction based on machine learning classification (Shiu et al., 2022). Mapped to FlyWire CB0038 in Shiu et al. (2024) supplement.
