a pathway over which a visual sensation is transmitted from the retina to the brain. A pathway consists of an optic nerve, the fibers of an optic nerve traveling through the optic chiasm to the lateral geniculate body of the thalamus, and optic radiations terminating in an occipital lobe. Each optic nerve contains fibers from only one retina.
The vast majority of the nerve fibres in the optic tract project to the lateral geniculate nucleus (LGN) in the dorsal part of the thalamus. The LGN is the main relay in the pathway to the primary visual cortex. The projection from the LGN to the visual cortex is called the optic radiation.
