LT34 [FBbt_20011442]

Adult lobula tangential neuron of the LT34 group (Nern et al., 2025). It receives input in the ipsilateral lateral accessory lobe, superior medial protocerebrum, anterior optic tubercle, mushroom body alpha’-lobe, lobula layer 6, gorget, epaulette, posterior ventrolateral protocerebrum, posterior lateral protocerebrum, superior clamp, inferior clamp, superior intermediate protocerebrum, superior posterior slope and lobula layer 5B, and the inferior bridge (Nern et al., 2025). It sends output to the ipsilateral superior medial protocerebrum, lobula layer 6, superior intermediate protocerebrum, superior posterior slope, lobula layer 5A and lobula layer 5B (Nern et al., 2025). Its predicted neurotransmitter is GABA (Eckstein et al., 2024; Nern et al., 2025). There is one of these cells per hemisphere (Nern et al., 2025).

Adult GABAergic Nervous system Visual system

Adult lobula tangential neuron of the LT34 group (Nern et al., 2025). It receives input in the ipsilateral lateral accessory lobe, superior medial protocerebrum, anterior optic tubercle, mushroom body alpha'-lobe, lobula layer 6, gorget, epaulette, posterior ventrolateral protocerebrum, posterior lateral protocerebrum, superior clamp, inferior clamp, superior intermediate protocerebrum, superior posterior slope and lobula layer 5B, and the inferior bridge (Nern et al., 2025). It sends output to the ipsilateral superior medial protocerebrum, lobula layer 6, superior intermediate protocerebrum, superior posterior slope, lobula layer 5A and lobula layer 5B (Nern et al., 2025). Its predicted neurotransmitter is GABA (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 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.
