General Information
Term adult CB2840 neuron ID (Ontology) FBbt:20006354 (Fly Anatomy)
Definition Adult brain-intrinsic neuron of the CB2840 group, with its soma in the brain, lateral to the anterior optic tubercle (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the VLPd1 hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral anterior ventrolateral protocerebrum, the ipsilateral posterior ventrolateral protocerebrum, the ipsilateral inferior clamp, the ipsilateral posterior lateral protocerebrum, the ipsilateral superior clamp, the ipsilateral superior lateral protocerebrum, the gnathal ganglia and the contralateral anterior ventrolateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the ipsilateral inferior clamp, the contralateral anterior ventrolateral protocerebrum, the ipsilateral anterior ventrolateral protocerebrum, the contralateral inferior clamp, the ipsilateral gorget, the contralateral gorget, the ipsilateral posterior ventrolateral protocerebrum and the ipsilateral mushroom body pedunculus (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024). There are approximately 3 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024).[ FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 ]
Also Known As "CB2840"
Comment Uncharacterized putative cell type from Schlegel et al. (2024), based on FlyWire v783 (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).
