receives synaptic input in region sends synaptic output to region sends synaptic output to cell lamina monopolar neuron L1 lamina monopolar neuron L2 lamina intrinsic neuron Lai optic cartridge outer photoreceptor cell FlyBrain_NDB:10111 An eye photoreceptor cell whose rhabdomere is part of the outer trapezoid of rhabdomeres of each ommatidium. There are six of these per ommatidium. Each has a single axon that projects along a single lamina optic cartridge within which it makes extensive synaptic connections before terminating in the proximal lamina. It is strongly presynaptic to lamina monopolar neurons L1 and L2 and the lamina intrinsic (amacrine) neuron (Rivera-Alba et al., 2011). fly_anatomy.ontology FBbt:00006007 VFB:FBbt_00006007 photoreceptor cell R1-6 eye photoreceptor cell
