Optic Tract

The optic tract is the extension of the visual system pathway that stretches from the optic chiasm to the lateral geniculate nucleus of the thalamus. The optic tract is a continuation of the optic nerves that cross over at the optic chiasm. Each optic tract contains axons from ganglion cells in the retinas of both the left and right eyes, but information from only one half of each eye's visual field.
