Arrange the following events in correct chronological order of their occurrence regarding the recognition of an object seen by our eyes:
| 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. |
