optic tract

optic lemniscus

Retinal ganglion cell axons that have passed through the optic chiasm continue as the optic tract, a predominantly white matter structure of the diencephalon. The tract is considered to extend from the optic chiasm and to terminate largely, though not exclusively, in the lateral geniculate complex; other fibres end in the superior colliculus and in further structures of the diencephalon, midbrain, and brainstem. This branching of destinations distinguishes the tract from a simple point-to-point relay, since visual information leaving it reaches both the thalamic route toward cortex and midbrain targets. Its alternative designation is the optic lemniscus, and it is classified as a tract of the diencephalon within the nervous system.

Diencephalic white matter (tract) which is comprised of retinal ganglion cell axons after which they have passed through the optic chiasm[ZFA]. Predominantly white matter structure found in diencephalon consisting of fibers originating in the retina. The optic tract is considered to extend from the point of the optic chiasm and terminates largely, although not exclusively, in the lateral geniculate complex. Other fibers end in the superior colliculus and other structures in the diencephalon, midbrain and brainstem (MM)[NIF].
