Trace the pathway of an image formed on the retina to the primary visual cortex in the brain
What will be an ideal response?
An image formed on the retina of each eye travels to the optic nerve via the axons of the retinal ganglion cells. The optic nerves meet at the optic chiasma, where axons from the nasal retinas cross to the opposite side. All axons from the opposite visual field then travel into the optic tract to the lateral geniculate nucleus in the thalamus. Axons from the lateral geniculate nucleus form optic radiations and terminate in the primary visual cortex in the medial occipital lobe. At this point, we become consciously aware of visual stimuli.
