General Information
Term adult anterior ventrolateral protocerebrum neuron 503 ID (Ontology) FBbt:20000612 (Fly Anatomy)
Definition Adult brain-intrinsic neuron of the AVLP503 group, with its soma in the brain, dorsal to the inferior posterior slope (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the VLPl&p2 posterior hemilineage (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in the ipsilateral anterior ventrolateral protocerebrum and the ipsilateral posterior ventrolateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the ipsilateral anterior ventrolateral protocerebrum and the ipsilateral 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 "AVLP503"
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).
