[英文釋義] The transducing of light energy to afferent nerve impulses,such as takes place in the retinal rods and cones. After light photons are absorbed by the photopigments,the signal is transmitted to the outer segment membrane by the cyclic GMP second messenger system,where it closes the sodium channels. This channel gating ultimately generates an action potential in the inner retina.
