What Is the Visual Pathway?

Visual pathway (visual pathway) visual physiological basis. Neural pathways for transmitting visual information. After the visual information undergoes preliminary processing by the retina, it converges in the tertiary visual neurons-optic ganglion cells, whose axons from the latter converge in the optic papilla of the retina to form the optic nerve and lead to the center. All optic nerve fibers from the nasal half of the retina cross to the contralateral side after passing through the optic cross, while the fibers from the half of the retinal side of the retina do not cross. After crossing and non-intersecting fibers, the optic tracts are reconstituted on both sides to reach the lateral geniculate nucleus of the thalamus. Half of the nerve fibers in the left and right optic tracts come from the non-intersecting fibers of the ipsilateral retinal temporal, and half of the nerve fibers from the contralateral retinal nasal. ^[1]
