Optic Nerve Type of Nerve: Chief Function(s) of Nerve: tract fibers. Sensory Vision The optic nerve , cranial nerve II, transmits visual information to occipital cortex. The nerve is easily found by locating a large "X-shaped" structure just caudal to the olfactory bulbs. The fibers anterior to the intersection of the "X", are optic nerve fibers. Axons caudal to the intersection, called the optic chiasm, are optic Take time now to consider these facts: • Axons from retinal cells in the lateral portions of the retina project to the optic chiasm, but they do not cross the midline. They remain ipsilateral and travel to occipital (visual) cortex on the ipsilateral side. • Axons from the medial, or nasal, regions of the retina enter the optic chiasm, cross the midline and project to the contralateral occipital cortex.
