In the OPL, the first synapses to appear are ribbon synapses between photoreceptor and HCs. Contacts are first established between cones and HCs, closely followed by wiring between rods and HCs. Vertical functional connections between photoreceptors and BCs arise later, once again starting with cones, and followed by rods.
