General Information
Term dorsal giant horizontal cell HSN ID (Ontology) FBbt:00003918 (Fly Anatomy)
Definition Horizontal system neuron whose dendritic arbor extends over the dorsal lobula plate (Scott et al., 2002). The area covered by its dendrite corresponds to the center of the large dorsal field of vision. It is electrically coupled to HSE and HSS (Schnell et al., 2010). There is one of these cells on each side (Shinomiya et al., 2022).[ FlyBase:FBrf0032046 FlyBase:FBrf0049410 FlyBase:FBrf0155898 FlyBase:FBrf0179400 FlyBase:FBrf0210299 FlyBase:FBrf0254308 ]
Also Known As "dorsal horizontal neuron" ; "horizontal system north" ; "horizontal system north cell" (for all, see Synonyms field below)
Comment Electrical coupling was shown indirectly by neurobiotin dye coupling in HSN and HSE cells labelled using the P\{GawB\}CG1090[NP0282] (FBti0033586) driver (Schnell et al., 2010). Due to their morphology and functional similarity, this cell is judged to be homologous to the dorsal horizontal system cell in larger flies (Heisenberg et al., 1978; Rajashekhar and Shamprasad, 2004; Scott et al., 2002).
