A list of steps involved in mechanism of vision is given below in a random order.
(i)Neural impulses are analysed and image formed on retina is recognised by visual cortex.
(ii)Membrane permeability changes
(iii)Ganglion cells are excited
(iv)Bipolar cells are depolarised
(v)Action potentials (impulse) are transmitted by optic nerves to visual cortex.
(vi)Potential differences are generated in the photoreceptor cells.
(vii)Light energy causes a change in shape of rhodopsin, leading to the dissociation of retina (an aldehyde of vitamin A ) from opsin (a protein)
(viii)Structure of opsin is changed.
Which of the following options represents these events in a correct order ?
