CB1891 [FBbt_20005487]

Adult brain-intrinsic neuron of the CB1891 group, with its soma in the brain, anterior to the antennal mechanosensory and motor center (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the VESa2 hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral vest, the ipsilateral wedge, the contralateral posterior lateral protocerebrum, the ipsilateral posterior lateral protocerebrum, the gnathal ganglia, the ipsilateral inferior clamp, the contralateral inferior clamp, the saddle and the ipsilateral inferior bridge (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the contralateral posterior lateral protocerebrum, the ipsilateral vest, the ipsilateral posterior lateral protocerebrum, the ipsilateral inferior clamp, the contralateral inferior clamp, the gnathal ganglia, the ipsilateral inferior bridge, the ipsilateral superior clamp, the ipsilateral wedge and the contralateral superior clamp (Schlegel et al., 2024; Dorkenwald et al., 2024). There are approximately 10 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024).

Adult Neuron lineage VESa2 BAlp1

Adult brain-intrinsic neuron of the CB1891 group, with its soma in the brain, anterior to the antennal mechanosensory and motor center (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the VESa2 hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral vest, the ipsilateral wedge, the contralateral posterior lateral protocerebrum, the ipsilateral posterior lateral protocerebrum, the gnathal ganglia, the ipsilateral inferior clamp, the contralateral inferior clamp, the saddle and the ipsilateral inferior bridge (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the contralateral posterior lateral protocerebrum, the ipsilateral vest, the ipsilateral posterior lateral protocerebrum, the ipsilateral inferior clamp, the contralateral inferior clamp, the gnathal ganglia, the ipsilateral inferior bridge, the ipsilateral superior clamp, the ipsilateral wedge and the contralateral superior clamp (Schlegel et al., 2024; Dorkenwald et al., 2024). There are approximately 10 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).
