General Information
Term adult lobula tangential neuron LT56 ID (Ontology) FBbt:20011453 (Fly Anatomy)
Definition Adult lobula tangential neuron of the LT56 group (Nern et al., 2025). It receives input in the ipsilateral lateral accessory lobe, lobula layer 2, lobula layer 3, lobula layer 4, lobula layer 6, gorget, epaulette, posterior ventrolateral protocerebrum, anterior ventrolateral protocerebrum, posterior lateral protocerebrum, inferior clamp, superior posterior slope, lobula layer 5A and lobula layer 5B (Nern et al., 2025). It sends output to the ipsilateral lobula layer 2, lobula layer 3, lobula layer 4, posterior ventrolateral protocerebrum, anterior ventrolateral protocerebrum, 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 is one of these cells per hemisphere (Nern et al., 2025).[ FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "LT56"
Comment Cell type identified in multiple EM datasets and at light level (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. Other information from Nern et al. (2025) supplements.
