- It is composed of two individual tracts, the left optic tract and the right optic tract, each of which conveys visual information exclusive to its respective contralateral half of the visual field.
- Robo receptors have also been shown to be crucial regulators of many other axon pathfinding decisions during development, including the projection of axons in the optic tract and in the olfactory epithelium.
- Visual information then enters the optic tract and travels to four different areas of the brain including the LGN, superior colliculus, pretectum of the mid brain and suprachiasmatic nucleus of the hypothalamus.
- The commissural fibers of the optic tract are called the commissure of Gudden in his honor, and he is credited for developing a specialized microtome for sectioning the brain for pathological study.
- It is composed of two individual tracts, the left optic tract and the right optic tract, each of which conveys visual information exclusive to its respective contralateral half of the visual field.
- The efferents of the telencephalic components of the lemnothalamic pathway project to the optic tectum ( equivalent to the superior colliculus ), the lemnothalamic visual nucleus, as well as other optic tract targets.
- The nasal fibers of each optic nerve decussate ( cross ) across the chiasm to the contralateral side while the temporal fibers course posteriorly to form the optic tract on the ipsilateral side.
- "' Mitohondrial optic neuropathies "'are a heterogenous group of disorders that present with visual disturbances resultant from mitochondrial dysfunction within the anatomy of the Retinal Ganglion Cells ( RGC ), optic nerve, optic chiasm, and optic tract.
- When split-brain patients are shown an image only in their left visual field ( the left half of what both eyes take in ( see optic tract ) ), they cannot vocally name what they have seen.

- The "'anterior perforated substance "'is an irregularly quadrilateral area in front of the optic tract and behind the olfactory trigone, from which it is separated by the fissure prima; medially and in front, it is continuous with the subcallosal gyrus; it is bounded laterally by the lateral stria of the olfactory tract and is continued into the uncus.
- This crossing is an adaptive feature of frontally oriented eyes, found mostly in predatory animals requiring precise visual depth perception . ( Prey animals, with laterally positioned eyes, have little binocular vision, so there is a more complete crossover of visual signals . ) Beyond the optic chiasm, with crossed and uncrossed fibers, the optic nerves become optic tracts.
