Where Are the Optic Radiations?

The optic radiations (ORs) carry visual information to the visual cortex. The tracts emanate from the lateral geniculate body

(LGN), run around the roof of the occipital horn of the lateral ventricle and terminate in the primary visual cortex in the calcarine sulcus.

Where is the left optic radiation?

For example, the left sided radiations contain information from the left temporal and right nasal retina. Temporal fibers synapse at layers 2, 3 and 5 of the lateral geniculate nucleus, while nasal fibers at layers 1, 4, and 6. The inferior fibers of the optic radiation correlate with the superior visual field.

Where is dorsal optic radiation?

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.
