Webcomprise the optic tract branch off to the superior colliculus--a structure in-volved with eye movements. The rest of the optic tract fibers synapse on cells in the lateral geniculate nucleus. Cells in the lateral geniculate nucleus send their axons in a bundle called the optic radiation to layer IV (one of six layers) of primary visual cortex.

His right superior quandrantanopia is due to a CVA involving the left temporal region of his optic radiation (Myers Loop) (see below), probably secondary to poorly controlled hypertension.
WebOptic tract. The left optic nerve and the optic tracts. In neuroanatomy, the optic tract (from Latin tractus opticus) is a part of the visual system in the brain. It is a continuation of the optic nerve that relays information from the optic chiasm to the ipsilateral lateral geniculate nucleus (LGN), pretectal nuclei, and superior colliculus.
WebThe axons of the retinal ganglion cells form the optic nerve. The two optic nerves meet at the optic chiasm, where the nerve fibers originating in the nasal retina of each eye decussate to join the temporal fibers of the fellow eye. From the chiasm, the same axons continue on as the optic tract. The …
