General Information
Term adult usnea subesophageal neuron ID (Ontology) FBbt:00051956 (Fly Anatomy)
Definition Adult local neuron with its soma in the lateral gnathal ganglion (Sterne et al., 2021). It has both dendritic and axonal arborization in the gnathal ganglion, with biased synapse distribution within this region (Sterne et al., 2021). It is bilateral, but most of its innervation is in the ipsilateral hemisphere (Sterne et al., 2021). It receives a large amount of input from gustatory neurons, mainly water- and sugar-sensing neurons, and responds to water stimulus (Shiu et al., 2022). Its activation results in proboscis extension (Shiu et al., 2022). It is predicted to be a GABAergic (Shiu et al., 2022) primary neuron (Dorkenwald et al., 2024; Schlegel et al., 2024). There are 2 of these cells per organism (Dorkenwald et al., 2024; Schlegel et al., 2024).[ FlyBase:FBrf0251280 FlyBase:FBrf0254006 ]
Also Known As "adult CB0008 neuron" ; "CB0008"
Comment Neurotransmitter prediction based on machine learning classification (Shiu et al., 2022). FlyWire CB0008 mapped to usnea in Shiu et al. (2024) - FBrf0260565 supplement.
