General Information
Term vertical system-like neuron VSm ID (Ontology) FBbt:00053494 (Fly Anatomy)
Definition Lobula plate tangential neuron that has dendrites resembling those of vertical system neurons 1/2, but with a smaller diameter and different axon terminals (Zhao et al., 2023). It receives input in a large anterior region of the visual field in lobula plate layer 4, from around 200 columns, and the dorsal part of layer 2, from around 50 columns (Zhao et al., 2023; 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). There are two of these cells on each side (Zhao et al., 2023).[ FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "vertical system-like neuron 1" ; "VS twin 1" ; "VSlike1" (for all, see Synonyms field below)
