Segregation of ipsilateral retinal ganglion cell axons at the optic chiasm requires the Shh receptor Boc.
The pattern of contralaterally and ipsilaterally projecting retinal ganglion cell (RGC) axons at the optic chiasm is essential for the establishment of binocular vision. Contralateral axons cross the chiasm midline as they progress from the optic nerve to the optic tract. In contrast, ipsilateral axons deviate from the chiasm and continue in the ipsilateral optic tract, avoiding the chiasm midl...
متن کاملEphrin-B Regulates the Ipsilateral Routing of Retinal Axons at the Optic Chiasm
In Xenopus tadpoles, all retinal ganglion cells (RGCs) send axons contralaterally across the optic chiasm. At metamorphosis, a subpopulation of EphB-expressing RGCs in the ventrotemporal retina begin to project ipsilaterally. However, when these metamorphic RGCs are grafted into embryos, they project contralaterally, suggesting that the embryonic chiasm lacks signals that guide axons ipsilatera...
متن کاملSpecific Routing of Retinal Ganglion Cell Axons at Optic Chiasm During Embryonic Development the Mammalian
During development of the mammalian CNS, axons encounter multiple pathway choices on their way to central target structures. A major pathway branch point in the visual system occurs at the optic chiasm, where retinal ganglion cell axons may either enter the ipsilateral or the contralateral optic tract. To investigate whether embryonic mouse retinal ganglion cell axons, upon reaching the optic c...
متن کاملDevelopmental determinants at the mammalian optic chiasm.
The mammalian optic chiasm is widely and properly regarded as a region where axons from the temporal retina take an uncrossed course and separate from axons arising in the nasal retina that take a crossed course. However, this is but a rough approximation of the adult situation, and developmental studies must take account of several distinctive stages and axon rearrangements that characterize t...
متن کاملGlioblastoma of the optic chiasm.
Primary malignant gliomas of the optic nerve and chiasm are rare, and are usually rapidly fatal in adults. We report a 48-year-old woman with a glioblastoma multiforme arising from the optic chiasm. Following radiotherapy, our patient survived nearly 14 months, which is the longest survival reported in patients with this diagnosis. There have only been four other reports of glioblastoma multifo...
