OPTIC CHIASM

the locale at the bottom of the brain where the optic nerves from both eyes meet each other. In humans, the nerve fibers from the nasal half of each retina intersect, so each hemisphere of the brain gathers input from both eyes. This partial intersection is referred to as a partial decussation.

OPTIC CHIASM: "Often, when optic chiasm malfunctions in humans, it is due to brain damage near the base of the brain."
