Brain: Optic tract

The left optic nerve and the optic tracts. The optic nerve, also called cranial nerve II, is the Nerve that transmits visual information from the Retina to the Brain.

The optic tract is a part of the visual system in the brain. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. This is a list of the subjects in Gray's Anatomy: IX Neurology The visual system is the part of the Nervous system which allows organisms to see. NeuroNames is a system of nomenclature for the human and/or macaque Brain. Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group The visual system is the part of the Nervous system which allows organisms to see. The brain is the center of the Nervous system in animals All Vertebrates and the majority of Invertebrates have a 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 optic nerve, also called cranial nerve II, is the Nerve that transmits visual information from the Retina to the Brain. The optic chiasm ( Greek χίασμα "crossing" from the Greek χλαζειν 'to mark with an X' after the Greek letter ' Χ ' chi) is the The lateral geniculate nucleus ( LGN) of the Thalamus is a part of the Brain, which is the primary processor of visual information received from the

Right vs. left

The relationships of the retinal fibers to the optic tracts are as follows:

optic tract	temporal retinal fibers	nasal retinal fiber
right optic tract	from the right eye	from the left eye
left optic tract	from the left eye	from the right eye

Pathology

A lesion in the left optic tract will cause right-sided homonomous hemianopsia. Homonymous hemianopsia is a medical term for a type of partial Blindness resulting in a loss of vision in the same Visual field of both Eyes
