The nerves that travel from the optic chiasm are the place in the brain where some of the optic nerve fibers cross into certain parts of the brain involved in vision.
It's a large bundle of nerve fibers of the visual pathway. It is a paired structure located on both left and right sides of the brain.
Each optic tract contains retinal ganglion cell axons that originate in the nasal half of the contralateral retina and the temporal half of the ipsilateral retina.
Most fibers end by synapsing with nerve cells in the lateral geniculate body which leads to image formation in the visual cortex.
