VST2 [FBbt_00048130]

Lobula plate tangential neuron that resembles vertical system neuron 3, with a dorsal extension into lobula plate layer 1 (Boergens et al., 2018; Zhao et al., 2023). It receives input in around 80 columns of lobula plate layer 4 and around 50 columns of layer 1 (Nern et al., 2025). It remains ipsilateral and its main output region is the inferior posterior slope (Dorkenwald et al., 2024; Schlegel et al., 2024). It is predicted to be cholinergic (Eckstein et al., 2024; Nern et al., 2025). There are four of these cells on each side (Zhao et al., 2023; Nern et al., 2025).
