The optic chiasm ( Greek χίασμα, "crossing", from the Greek χλαζειν 'to mark with an X', after the Greek letter ' Χ ', ''chi'') is the part of the Brain where the Optic Nerve s partially cross.


PATHWAYS

Specifically, the nerves connected to the right eye that attend to the left visual field cross with the nerves from the left eye that attend to the right visual field.

The parts of both Eyes that attend to the right visual field are processed in the left Visual System in the brain, and vice versa.
