Mechanism of vision includes following steps in random order A. Generates action potential in ganglionic cells through the bipolar cells. B. Membrane permeabilities of rods and cones change. C. Light induces dissociation of retinal from opsin. D. Activation of photopigment of rods and cones. E. Light rays focussed on the retina. F. Potential differences generated in photoreceptor cells. G. Image formed on retina is recognized by the brain. H. Action potentials are transmitted by optic nerve to the visual cortex of brain. The correct sequence is

Given below are the stages in the generation of optic nerve impulse or action potential on the retina and the role of opsin and retinal in the mechanism of vision. Arrange them in a sequential order. a) Action potential (impulses) are transmitted by the optic nerves to the visual cortex area of the brain. b) Light induces dissociation of retinal from opsin. c) Generates action potential in the ganglion cells through bipolar cells. d) Structural changes in the opsin which induce membrane permeability changes. e) Potential differences are generated in the photoreceptor cells. f) Neural impulses are analyzed by visual cortex area of the brain.
