General Information
Term lamina intrinsic neuron ID (Ontology) FBbt:00003746 (Fly Anatomy)
Definition Intrinsic 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).[ FlyBase:FBrf0049410 FlyBase:FBrf0159582 FlyBase:FBrf0216925 FlyBase:FBrf0244935 ]
Also Known As "Lai"
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 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).
