The (
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.
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.
