IB118 [FBbt_20001295]

Adult brain-intrinsic neuron of the IB118 group, with its soma in the brain, near to the mushroom body calyx (Schlegel et al., 2024; Dorkenwald et al., 2024). It is a putative embryonic-born neuron (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral superior posterior slope, the contralateral superior posterior slope, the ipsilateral inferior bridge and the contralateral inferior bridge (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the contralateral superior posterior slope, the contralateral inferior bridge, the contralateral inferior clamp and the ipsilateral superior posterior slope (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is serotonin (Eckstein et al., 2024). There are approximately 2 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024).

Adult Nervous system Serotonergic primary neuron

Adult brain-intrinsic neuron of the IB118 group, with its soma in the brain, near to the mushroom body calyx (Schlegel et al., 2024; Dorkenwald et al., 2024). It is a putative embryonic-born neuron (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral superior posterior slope, the contralateral superior posterior slope, the ipsilateral inferior bridge and the contralateral inferior bridge (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the contralateral superior posterior slope, the contralateral inferior bridge, the contralateral inferior clamp and the ipsilateral superior posterior slope (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is serotonin (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).
