Explanation:
Detailed explanation-1: -Visual processing and, ultimately, visual fields begin in the retina. Light enters the eye; passes through the cornea, anterior chamber, lens, and vitreous; and finally reaches the photoreceptor cells of the retina. Light activates these photoreceptors, which modulate the activity of bipolar cells.
Detailed explanation-2: -Three stages of visual processing determine how internal noise appears to an external observer: light adaptation, contrast gain control and a postsensory/decision stage.
Detailed explanation-3: -So the correct option is ‘Photosensorycells→Bipolarneurons→Ganglioniccells→Sensorynerves’.
