SMP021 [FBbt_20002883]

Adult brain-intrinsic neuron of the SMP021 group, with its soma in the brain, near to the anterior optic tubercle (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the AOTUv3 dorsal hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral superior medial protocerebrum, the ipsilateral superior intermediate protocerebrum and the ipsilateral anterior optic tubercle (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the ipsilateral inferior bridge, the contralateral inferior bridge, the ipsilateral superior medial protocerebrum and the ipsilateral superior intermediate protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024). There are approximately 7 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024).

Adult Cholinergic lineage AOTUv3 DALcl1

Adult brain-intrinsic neuron of the SMP021 group, with its soma in the brain, near to the anterior optic tubercle (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the AOTUv3 dorsal hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral superior medial protocerebrum, the ipsilateral superior intermediate protocerebrum and the ipsilateral anterior optic tubercle (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the ipsilateral inferior bridge, the contralateral inferior bridge, the ipsilateral superior medial protocerebrum and the ipsilateral superior intermediate protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024). There are approximately 7 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024).

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).
