Optic tract

The optic tract refers to the optic nerve after half of the fibers have crossed sides at the optic chiasm. However, it still consists of the axons (long fiber-like extensions) of the retinal ganglion cells. Most of the optic tract ends in the lateral geniculate nucleus, while others end in the superior colliculi, among other places.

Visual pathway

The visual pathway refers to the network of nerve cells involved in visual perception. In mammals, it runs from the retinal ganglion cells in the eye – as the optic nerve to the optic chiasm, then as the visual tract – via the only switching point in the lateral geniculate nucleus to the primary visual cortex.
