General Information
Term	adult anterior ventrolateral protocerebrum neuron 255	ID (Ontology)	FBbt:20000364 (Fly Anatomy)
Definition	Adult brain-intrinsic neuron of the AVLP255 group, with its soma in the brain, near to the accessory medulla (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the LALa1 anterior hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral anterior ventrolateral protocerebrum, the ipsilateral superior lateral protocerebrum, the ipsilateral inferior clamp, the contralateral inferior clamp, the contralateral epaulette and the contralateral gorget (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the contralateral inferior clamp, the ipsilateral inferior clamp, the contralateral epaulette, the ipsilateral epaulette, the ipsilateral anterior ventrolateral protocerebrum, the contralateral gorget, the ipsilateral gorget and the contralateral vest (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is gaba (Eckstein et al., 2024). There are approximately 3 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024).[ FlyBase:FBrf0246888 FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 ]
Also Known As	"AVLP255"
Comment	Uncharacterized putative cell type based on Hemibrain data (Scheffer et al., 2020) and updated using FlyWire (FAFB) data (Dorkenwald et al., 2024; Schlegel et al., 2024). Soma locations are based on the closest annotated neuropil region. Pre- or post-synapse locations are the fewest regions that collectively contain at least 80 percent of all pre- or post-synapses of these neurons in FlyWire. Neurotransmitter predictions are from Eckstein et al. (2024). Other annotations are based on annotations in FlyWire and are available in the supplemental material of Schlegel et al. (2024).
