Optic tract
From Wikipedia, the free encyclopedia
Image:Gray773.png The optic tract is a part of the visual system in the brain.
It is a continuation of the optic nerve and runs from the optic chiasm (where half of the information from each eye crosses sides, and half stays on the same side) to the lateral geniculate nucleus. The right optic tract consists of temporal retinal fibers from the right eye and nasal retinal fibers from the left eye; conversely, the left optic tract consists of temporal retinal fibers from the left eye and nasal retinal fibers from the right eye. A lesion in the left optic tract will cause right-sided homonomous hemianopsia.
