VS5

ID: FBbt_00007521

Vertical system neuron whose dendritic branching pattern is simple and predominantly limited to the dorsal lobula plate. This neuron projects at least two major dendritic branches dorsally, one from the initial dorsal extension, and one from a major branch that initially grows into the central lobula before contributing a dorsally extending branch. Its dendritic tree extends much more anteriorly than that of other ventral system neurons (Scott et al., 2002). Its receptive field of vision is in between the receptive fields of VS4 (more frontal) and VS6 (more lateral). It is electrically coupled to VS4 and VS6 (Joesch et al., 2008).

Electrical 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 VS7-VS10 cells in the blowfly (Scott et al., 2002).
