SMP421 [FBbt_20003283]

Adult brain-intrinsic neuron of the SMP421 group, with its soma in the brain, dorsal to the superior lateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the CLp1 hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral superior medial protocerebrum and the ipsilateral mushroom body calyx (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the ipsilateral superior medial protocerebrum (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 CLp1 DPLc4

Adult brain-intrinsic neuron of the SMP421 group, with its soma in the brain, dorsal to the superior lateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the CLp1 hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral superior medial protocerebrum and the ipsilateral mushroom body calyx (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the ipsilateral superior medial protocerebrum (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 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).
