Which structure transmits visual information from the eye to the brain?

• A. Optic nerve
• B. Retina
• C. Cornea
• D. Lens

Answer: (A)

How visual information travels from the eye to the brain. Light is detected by photoreceptors in the retina and converted into electrical signals. Those signals are then carried out of the retina by the axons of ganglion cells, which form the optic nerve. This nerve bundles the neural information and transmits it toward the brain, where it reaches the visual-processing areas for interpretation. The cornea and lens are involved in focusing light onto the retina, but they do not carry neural signals to the brain. The retina itself detects light but transmits the information to the brain via the optic nerve, making the optic nerve the structure that transmits visual information from the eye to the brain.
