IB109 [FBbt_20001286]

Adult brain-intrinsic neuron of the IB109 group, with its soma in the brain, ventral to the mushroom body calyx (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the SMPp&v1 ventral hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral inferior clamp, the ipsilateral inferior bridge, the ipsilateral superior medial protocerebrum, the ipsilateral superior clamp, the contralateral inferior bridge and the contralateral inferior clamp (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the contralateral inferior bridge, the ipsilateral inferior clamp, the ipsilateral inferior bridge, the contralateral antler, the ipsilateral antler, the ipsilateral superior posterior slope, the ipsilateral superior medial protocerebrum and the contralateral inferior clamp (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is glutamate (Eckstein et al., 2024). There are approximately 2 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024).

Adult Glutamatergic lineage SMPp&v1 DPLc5

Adult brain-intrinsic neuron of the IB109 group, with its soma in the brain, ventral to the mushroom body calyx (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the SMPp&v1 ventral hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral inferior clamp, the ipsilateral inferior bridge, the ipsilateral superior medial protocerebrum, the ipsilateral superior clamp, the contralateral inferior bridge and the contralateral inferior clamp (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the contralateral inferior bridge, the ipsilateral inferior clamp, the ipsilateral inferior bridge, the contralateral antler, the ipsilateral antler, the ipsilateral superior posterior slope, the ipsilateral superior medial protocerebrum and the contralateral inferior clamp (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is glutamate (Eckstein et al., 2024). There are approximately 2 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).
