General Information
Term adult lobula columnar neuron LC39a ID (Ontology) FBbt:20011396 (Fly Anatomy)
Definition Adult lobula columnar neuron of the LC39a group (Nern et al., 2025). It belongs to the VPNp&v1 ventral hemilineage (Nern et al., 2025). It receives input in the ipsilateral lobula layer 4, lobula layer 6, posterior lateral protocerebrum, inferior clamp, lobula layer 5A and lobula layer 5B (Nern et al., 2025). It sends output to the ipsilateral lobula layer 6, posterior lateral protocerebrum, inferior clamp, superior posterior slope, lobula layer 5A and lobula layer 5B (Nern et al., 2025). Its predicted neurotransmitter is glutamate (Eckstein et al., 2024; Nern et al., 2025). There are approximately 3 of these cells per hemisphere (Nern et al., 2025).[ FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "LC39a"
Comment Cell type identified in multiple EM datasets (Schlegel et al., 2024; Dorkenwald et al., 2024; Nern et al., 2025). Synapse locations are given where each cell of this type in neuprint has at least 10 connections. Hemilineage information from neuprint, though original source not clear. Other information from Nern et al. (2025) supplements.
