Final answer:
The right visual field is projected onto the left half of each eye and is then processed by the left hemisphere's LGN due to the decussation of fibers at the optic chiasm.
Step-by-step explanation:
The right visual field projects to the left half of each eye and then is analyzed by the LGN in the left hemisphere. This occurs because the axons from the medial side of the retina (which process information from the lateral visual field) decussate, or cross over, at the optic chiasm to the opposite side of the brain. In contrast, the axons from the lateral side of the retina (processing the medial visual field) do not decussate and project to the same side of the brain. The segregation of visual information at the optic chiasm ensures that the left visual cortex processes the right visual field and the right visual cortex processes the left visual field. This arrangement allows for the representation of visual fields in the brain to maintain a topographic relationship throughout the visual pathway—to the lateral geniculate nucleus (LGN) and then to the primary visual cortex in the occipital lobe.
