General Information
Term adult superior medial protocerebrum neuron 252 ID (Ontology) FBbt:20003114 (Fly Anatomy)
Definition Adult brain-intrinsic neuron of the SMP252 group, with its soma in the brain, lateral to the mushroom body calyx (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the SMPpv2 dorsal hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral superior medial protocerebrum, the contralateral superior medial protocerebrum, the ipsilateral superior lateral protocerebrum and the contralateral superior lateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the contralateral superior medial protocerebrum, the ipsilateral superior medial protocerebrum and the contralateral superior lateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024). There are approximately 2 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024).[ FlyBase:FBrf0246888 FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 ]
Also Known As "SMP252"
Comment 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).
