WebThe magnocellular pathways are involved in processing movement and contrast, while the parvocellular pathways are involved in the perception of color and fine detail. It is likely that Jane will have difficulty perceiving movement and contrast in her right visual field, as well as difficulty perceiving color and fine detail in her left visual field. WebFollowing the early visual pathway Think of the visual pathway like a highway, with neurons as the cars and your vision as the driver. Ideally, the pathway is smooth and efficient, with predictable curves and directions leading from your optic nerve to your occipital lobe’s primary visual cortex.
