General Information
Term	adult lobula columnar neuron LC44	ID (Ontology)	FBbt:20011401 (Fly Anatomy)
Definition	Adult lobula columnar neuron of the LC44 group (Nern et al., 2025). It belongs to the VLPp&l1 lateral hemilineage (Nern et al., 2025). It receives input in the ipsilateral lobula layer 6, posterior lateral protocerebrum and lobula layer 5B (Nern et al., 2025). It sends output to the ipsilateral lobula layer 6 and posterior lateral protocerebrum (Nern et al., 2025). Its predicted neurotransmitter is acetylcholine (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	"LC44"
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.
