(2018) judged to correspond to VST1 from Zhao et al. (2023) based on LOP layer 4 restricted innervation. Lobula plate tangential neuron that resembles vertical system neuron 2, having little lobula plate arborization outside of layer 4, but with a smaller diameter and sparser dendrites (Boergens et al., 2018). It additionally has a main branch in the ventral part of the dendrite (Boergens et al., 2018). It receives input in around 100 columns of lobula plate layer 4, remains ipsilateral, and sends output mainly to the inferior posterior slope (Dorkenwald et al., 2024; Schlegel et al., 2024; Nern et al., 2025). It is predicted to be cholinergic (Eckstein et al., 2024; Nern et al., 2025). There are two of these cells on each side (Zhao et al., 2023; Nern et al., 2025). fly_anatomy.ontology FBbt:00048129 VST1 VST1 VS twin 1 vertical system-like neuron 1 adult visual projection neuron adult cholinergic neuron unilateral
