Definition |
Astrocyte-like (reticular) glial cell of the adult lamina (Edwards et al., 2012; Kremer et al., 2017). Each cell contributes to the wrapping of multiple columns and each column is wrapped by multiple glia (Edwards et al., 2012; Kremer et al., 2017). Epithelial glial cells elaborate numerous fine processes into the lamina plexus, especially from the surface juxtaposing the R1-R6 growth cones or axon termini (Poeck et al., 2001). In the lamina, they receive a small amount of synaptic input from each of photoreceptors R1-R6 and strong input from lamina intrinsic (amacrine) cells (Rivera-Alba et al., 2011). There are around 470 of these cells per lamina (Kremer et al., 2017).[ FlyBase:FBrf0055906 FlyBase:FBrf0134808 FlyBase:FBrf0205531 FlyBase:FBrf0209968 FlyBase:FBrf0210316 FlyBase:FBrf0234767 ] |
Also Known As |
"adult lamina astrocyte-like glial cell" ; "adult lamina reticular glial cell" ; "L-ALG" |
Comment |
Cell connectivity in the lamina was determined by analysis of semi-automated EM reconstruction of 749 serial sections of 21 complete lamina cartridges. The number of synaptic connections for a epithelial glial cell (presynaptic/postsynaptic) in a single lamina cartridge for each cell type was the following: R1 (-/15), R2 (-/13), R3 (-/7), R4 (-/9), R5 (-/10), R6 (-/11), Lai (-/87) (Rivera-Alba et al., 2011). |
