adult lamina epithelial glial cell [FBbt_00100513]

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. (Poeck et al., 2001, Winberg et al., 1992, Hamanaka and Meinertzhagen, 2010, Edwards and Meinertzhagen, 2010, Takemura et al., 2008, Kremer et al., 2017)

Astrocyte-like (reticular) glial cell of the adult lamina (Edwards et al., 2012; Kremer et al., 2017.

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).
