Fibers pass through vertical and horizontal gaze centers and the Superior colliculi. Brodmann areas 17, 18, and 19 in the human brain are visual cortices of the occipital lobe. Brodmann's area 47. Many of the areas Brodmann defined based solely on their neuronal organization have since been correlated closely to diverse cortical functions.
