Optic Tract

Optical channel is one of the two bundles of nerve fibers that extend from the optic chiasm to the brain peduncles, where it divides into the root and the other half, which ended in the superior colliculus and lateral geniculate body, respectively. As an optical channel is a continuation of the optic nerve, its function is to tranmistir visual sensory information coming from the retina to the brain (accipital lobe). If the lesion in one optical channel, this will lead to hemianopsia, which is half blind eye visual field accordingly.
