Optic tract - Wikipedia
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. It is composed of two individual tracts, the left optic tract and the right optic tr… WebOptic nerves project posteriorly to form the optic chiasm and continue as the optic tract. Axons from the temporal hemiretinas (nasal visual hemifields) project posteriorly in the IPSILATERAL optic tract (because it's contingent on the retina).
