Question :Choose correct sequence of mechanism of visioni. The light rays in visible wavelength focussed on the retina through the cornea and lens.ii. Light induces dissociation of the retina from opsin resulting in changes in the structure of the opsin iii. This causes membrane permeability changes iv. Potential differences are generated in the photoceceptor cells rods and cones v. This produces a signal that generates action potentials in the ganglion cells through the bipolar cells.vi. These action potentials (impulses) are transmitted by the optic nerves to the visual cortex area of the brainvii.
