Term |
equatorial giant horizontal cell HSE |
ID (Ontology) |
FBbt:00003919 (Fly Anatomy) |
Definition |
Horizontal system neuron whose dendritic arbor extends over the central lobula plate (Scott et al., 2002). It has both synaptic input and output in the axon terminal in the protocerebral region (Raghu et al., 2007). The area covered by its dendrite corresponds to the center of the large equatorial field of vision. It is electrically coupled to HSN 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:FBrf0200428 FlyBase:FBrf0207482 FlyBase:FBrf0210299 FlyBase:FBrf0254308 ] |
Also Known As |
"horizontal system equatorial cell" ; "HS equatorial" ; "HSE" |
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). The postsynaptic terminals in the protocerebral region were identified by the presence of a subunit of the GABA receptor (Rdl) in horizontal system cells labelled with P\{UAS-Rdl.HA\} (FBtp0021350] driven by the P\{GAL4\}3A driver [FBti0131277) (Raghu et al., 2007). Due to their morphology and functional similarity, this cell is judged to be homologous to the equatorial horizontal system cell in larger flies (Heisenberg et al., 1978; Rajashekhar and Shamprasad, 2004; Scott et al., 2002). |
