optic tract
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]. [ http://en.wikipedia.org/wiki/Optic_tract http://zfin.org/curator ]

relationships need checking by expert. NIF and ZFA both state part of diencepahalon; MA says part of optic nerve II. in uberon, CNS and PNS are spatially disjoint, and axon tracts are part of the CNS so we make the relationship to CNII 'continuous_with'
