I. | Light induces dissociation of retinal from opsin. |
II. | There is a change in the permeability of the membrane of photoreceptors. |
III. | Potential differences are generated in the photoreceptor cells. |
IV. | Action potential is generated in the ganglion cells through the bipolar cells. |
V. | Optic nerve transmits impulse to visual cortex. |
VI. | Neural impulses are analysed and the image formed on the retina is recognised based on earlier memory or experience. |
