Examples
- The optic tract is a part of the visual pathway that carries visual information from the optic chiasm to the lateral geniculate nucleus in the thalamus.
- Damage to the optic tract can result in visual field defects, including homonymous hemianopia, where a person loses half of their visual field on the same side in both eyes.
- The optic tract is formed by the combination of the optic nerves from each eye at the optic chiasm, where the nasal fibers from each eye cross over to the opposite side.
- The optic tract is responsible for transmitting visual information from the retina to the brain, where it is processed and interpreted.
- Lesions in the optic tract can be caused by various factors, including tumors, strokes, and traumatic brain injuries, which can lead to visual disturbances and other neurological symptoms.
