Axons of ganglion cells from halves of both retinas cross in the . Some of these axons project to the of the thalamus, and then to of the occipital lobe, where the brain interprets an object is. Others project to the of the midbrain, where the brain interprets an object is. Axons of ganglion cells from halves of both retinas travel in the , rather than crossing over to the opposite side of the brain. Some of these axons project to the of the thalamus, and the remainder travel to the of the midbrain. In summary, the lateral geniculate nucleus and superior colliculus on each side of the brain receive axons from the half of the eye on the opposite side, and the half of the eye on the same side.
