CB2909 [FBbt_20006418]

Adult brain-intrinsic neuron of the CB2909 group, with its soma in the brain, near to the protocerebral bridge (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the DM1 dorsal hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the contralateral superior posterior slope, the ipsilateral superior posterior slope, the contralateral inferior clamp and the contralateral posterior lateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the contralateral superior posterior slope, the ipsilateral superior posterior slope, the ipsilateral inferior clamp, the contralateral posterior lateral protocerebrum and the contralateral inferior clamp (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).

Adult Cholinergic lineage DM1 DPMm1

Adult brain-intrinsic neuron of the CB2909 group, with its soma in the brain, near to the protocerebral bridge (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the DM1 dorsal hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the contralateral superior posterior slope, the ipsilateral superior posterior slope, the contralateral inferior clamp and the contralateral posterior lateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the contralateral superior posterior slope, the ipsilateral superior posterior slope, the ipsilateral inferior clamp, the contralateral posterior lateral protocerebrum and the contralateral inferior clamp (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).

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).
