Identifier Name Description
FBbt:00004215 photoreceptor cell R2 Outer photoreceptor cell of the adult eye whose rhabdomere is located in the middle of the longer of the two parallel sides of the trapezoid of rhabdomeres in each ommatidium. It has a single axon that projects along a single lamina optic cartridge (Fischbach and Dittrich, 1989; Wolff and Ready, 1993) within which it makes extensive presynaptic connections with the lamina monopolar cells L1-L3, lamina intrinsic (amacrine) cells and columnar neuron T1, before terminating in the proximal lamina. It also establishes connections with epithelial and surface glial cells The photoreceptor R2 receives input from L2, L4 (collaterals from adjacent columns), lamina intrinsic (amacrine) cells and lamina wide-field neurons Lawf (Rivera-Alba et al., 2011).
