Optic chiasm
The optic chiasm is a cross-shaped junction between the optic nerves, where 50% of the optic nerve fibers change sides.

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.

The visual system is the part of the nervous system that processes visual information. It primarily comprises the eye, the optic nerve, the optic chiasm, the optic tract, the lateral geniculate nucleus, the optic radiation, the primary visual cortex, and the visual association cortices.

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.
