General Information
Term vertical system neuron 3 ID (Ontology) FBbt:00007519 (Fly Anatomy)
Definition Vertical system neuron with both dorsally and ventrally sweeping major branches and whose dorsal dendritic tree extends anteriorly and posteriorly. Unlike vertical system neuron 2, its dorsal dendrites continue to slant laterally as they extend dorsally and have a major component that extends anteriorly (Scott et al., 2002). Its receptive field of vision is in between the receptive fields of VS2 (more frontal) and VS4 (more lateral). It is electrically coupled to VS2 and VS4 (Joesch et al., 2008).[ FlyBase:FBrf0155898 FlyBase:FBrf0204334 ]
Also Known As"LPT07" ; "VS3" ; "VS3 neuron"
CommentElectrical coupling was shown indirectly by neurobiotin dye coupling in vertical system cells labelled using the P\{GAL4\}DB331 driver (FBti0115113) (Joesch et al., 2008). Due to its morphology and functional similarity, this cell is judged to be homologous to the VS2-VS6 cells in the blowfly (Scott et al., 2002).
