The number of synaptic connections for Lai (presynaptic/postsynaptic) in a single lamina cartridge with each cell type was the following: R1 (-/36), R2 (1/39), R3 (-/39), R4 (2/37), R5 (2/35), R6 (-/40), L1 (1/-), L2 (1/-), L3 (10/-), L4 (4/2), L5 (4/-), Lai (1), T1 (54/1), C2 (1/5), C3 (1/9), Lawf (-/24) and epithelial glia (87/-) (Rivera-Alba et al., 2011). Am fly_anatomy.ontology VFB:FBbt_00003746 Intrinsic amacrine neuron of the lamina with arborizations spanning the proximal and distal lamina, whose cell body lies proximal to the lamina (Fischbach and Dittrich, 1989; Meinertzhagen and Sorra, 2001). It has extensive arborizations and forms a substantial number of presynaptic terminals with columnar neuron T1 and epithelial glia (Rivera-Alba et al., 2011). It receives strong input from each of photoreceptors R1-R6, and from lamina wide-field cells (Rivera-Alba et al., 2011). It is a glutamatergic neuron (Davis et al., 2020). There are approximately 210 of these cells on each side (Nern et al., 2025).
