Final answer:
Vision goes through three neuronal structures: the optic nerve, the lateral geniculate nucleus, and the visual cortex.
Step-by-step explanation:
Vision goes through three neuronal structures: the optic nerve (or optic tract), the lateral geniculate nucleus of the thalamus, and the visual cortex located in the occipital lobe of the cerebrum.
The optic nerve carries visual information from the retina to the thalamus, specifically the lateral geniculate nucleus. From the lateral geniculate nucleus, axons project to the visual cortex in the occipital lobe, where visual perception takes place.
Another target of the optic nerve is the superior colliculus, which is involved in coordinating eye movements and integrating auditory information.
