Question: What is the main difference and cause for ON vs OFF pathways in the retina? Question options: Horizontal cells induce lateral inhibition only for the OFF pathway Photoreceptors hyperpolarize with light for the OFF pathway and depolarize with light for the ON pathway The ON pathway is functional under high luminance conditions and the OFF pathway is functional under low luminance conditions Glutamate depolarizes OFF-bipolar cells via ionotropic receptors and glutamate hyperpolarizes ON-bipolar cells via mGluR receptors The ON pathway uses rods and the OFF pathway uses cones
