LT61b

ID: FBbt_20011458

Adult lobula tangential neuron of the LT61b group (Nern et al., 2025). It belongs to the VLPl2 lateral hemilineage (Nern et al., 2025). It receives input in the ipsilateral lobula layer 2, lobula layer 3, lobula layer 4, lobula layer 6, posterior ventrolateral protocerebrum, anterior ventrolateral protocerebrum, lobula layer 5A and lobula layer 5B, and the contralateral posterior ventrolateral protocerebrum and anterior ventrolateral protocerebrum (Nern et al., 2025). It sends output to the ipsilateral lobula layer 3, lobula layer 4, posterior ventrolateral protocerebrum, anterior ventrolateral protocerebrum, posterior lateral protocerebrum and lobula layer 5A, and the contralateral posterior ventrolateral protocerebrum and anterior ventrolateral protocerebrum (Nern et al., 2025). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024; Nern et al., 2025). There is one of these cells per hemisphere (Nern et al., 2025).

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.
