LT55 [FBbt_20011452]

Adult lobula tangential neuron of the LT55 group (Nern et al., 2025). It receives input in the ipsilateral lobula layer 6, posterior lateral protocerebrum and lobula layer 5B, and the contralateral anterior optic tubercle and lobula layer 6 (Nern et al., 2025). It sends output to the ipsilateral lobula layer 6, and the contralateral anterior optic tubercle and lobula layer 6 (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).
