Wikipedia
Optic radiation
In neuroanatomy, the optic radiation (also known as the geniculocalcarine tract, the geniculostriate pathway, and posterior thalamic radiation) are axons from the neurons in the lateral geniculate nucleus to the primary visual cortex. The optic radiation receives blood through deep branches of the middle cerebral artery and posterior cerebral artery. They carry visual information through two divisions (called upper and lower division) to the visual cortex (also called striate cortex) along the calcarine fissure. There is one set of upper and lower divisions on each side of the brain. If a lesion only exists in one unilateral division of the optic radiation, the consequence is called quadrantanopia, which implies that only the respective superior or inferior quadrant of the visual field is affected. If both divisions on one side of the brain are affected, the result is a contralateral homonymous hemianopsia.

optic radiation
The optic radiation (also known as the geniculocalcarine tract) is a component of the visual system in the brain. It is a collection of nerve fibers that transmit visual information from the lateral geniculate nucleus in the thalamus to the primary visual cortex in the occipital lobe. These radiations are responsible for carrying information related to color, contrast, brightness, and movement. Dysfunction or damage to the optic radiations can result in various types of visual field loss.
