| Term | vertical system twin neuron 1 | ID (Ontology) | FBbt:00048129 (Fly Anatomy) |
| Definition | 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).[ FlyBase:FBrf0240805 FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ] | ||
| Also Known As | "vertical system-like neuron 1" ; "VS twin 1" ; "VSlike1" (for all, see Synonyms field below) | ||
| Comment | VSlike1 from Boergens et al. (2018) judged to correspond to VST1 from Zhao et al. (2023) based on LOP layer 4 restricted innervation. | ||
