May be renamed when better described in future. May only be one of these per hemisphere and may be identical to OA-AL2i1 (Kandimalla et al., 2023 - FBrf0257023). FBbt:00051233 P1-9 PB octopaminergic neuron VFB:FBbt_00051233 Neuron with extensive innervation of the brain that has a sinuous arbor of variable density that courses through all glomeruli of the protocerebral bridge (PB) (Wolff and Rubin, 2018). It has its cell body in the subesophageal zone (Kandimalla et al., 2023). There is heterogeneity in the brain regions innervated and whether PB innervation is unilateral or bilateral (Wolff and Rubin, 2018). At least one subtype is octopaminergic (Busch et al., 2009; Wolff and Rubin, 2018). P1-9 adult interneuron octopaminergic AL2i1 neuron adult subesophageal zone
