Where do the optic nerves converge?

• Optic chiasm

• Retina

• Cornea

• Lens

What is the role of the optic chiasm?

• To focus light

• To split visual information into left and right fields

• To produce electrical signals

• To control eye movement

How does the brain process visual information from both eyes?

• Separately for each eye

• By merging the information at the optic chiasm

• By focusing only on the left eye

• By ignoring one eye

What is the final destination of visual information in the brain?

• Lens

• Optic chiasm

• Retina

• Primary visual cortex
