| Term | adult octopaminergic AL2b1 neuron | ID (Ontology) | FBbt:00110146 (Fly Anatomy) |
| Definition | Octopaminergic neuron of the AL2 cluster which innervates the ipsilateral and contralateral lobula (Busch et al., 2009). It has greater innervation of the contralateral lobula, with mixed pre- and post- synapses in layers 5 and 6, spanning around 100 columns (Nern et al., 2025). It has its soma ventral-medial to the antennal lobe and is a putative embryonic-born neuron (Schlegel et al., 2024; Dorkenwald et al., 2024). Its main process extends posteriodorsally from the soma, close to the esophageal foramen, then bifurcates in the posterior brain, projecting to both optic lobes (Busch et al., 2009; Dorkenwald et al., 2024; Schlegel et al., 2024; Nern et al., 2025). In the central brain, it receives input in the superior posterior slope, posterior lateral protocerebrum and cantle (Schlegel et al., 2024; Dorkenwald et al., 2024). There is one of these cells per hemisphere (Nern et al., 2025).[ FlyBase:FBrf0207458 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ] | ||
| Also Known As | "adult posterior lateral protocerebrum neuron 244" ; "LoVCLo3" ; "OA-AL2b1" (for all, see Synonyms field below) | ||
| Comment | The neurotransmitter was assessed by immunostaining with an anti-octopamine (OA) antibody in cells labelled with tdc2-GAL4 (FBti0101786) and NP7088-GAL4 (Busch et al., 2009). Mapped to EM data in Nern et al. (2025) and Schlegel et al. (2024). | ||
