General Information
Term adult lobula tangential neuron LT81 ID (Ontology) FBbt:20011477 (Fly Anatomy)
Definition Adult lobula tangential neuron of the LT81 group (Nern et al., 2025). It belongs to the VPNp1 lateral hemilineage (Nern et al., 2025). It receives input in the ipsilateral lobula layer 6, and the contralateral posterior lateral protocerebrum (Nern et al., 2025). It sends output to the contralateral posterior lateral protocerebrum and superior posterior slope (Nern et al., 2025). There are approximately 6 of these cells per hemisphere (Nern et al., 2025).[ FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "LT81"
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. Hemilineage information from neuprint, though original source not clear. Other information from Nern et al. (2025) supplements.
