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.
