Which cortical lobe processes vision?

• A. Cortex, Frontal lobe
• B. Cerebellum
• C. Cortex, Occipital lobe
• D. Brainstem

Answer: (C)

Vision processing takes place in the occipital lobe of the cerebral cortex. The primary visual cortex, located along the calcarine fissure, receives input from the retina via the optic tracts and the thalamus (lateral geniculate nucleus). This cortical area handles the initial interpretation of visual features like light, edges, and basic shapes, which is then refined by adjacent visual areas for more complex tasks such as object recognition and spatial location. The frontal lobe isn’t primarily responsible for vision, the cerebellum coordinates movement, and the brainstem houses basic autonomic and relay functions. So the cortical region that processes vision is the occipital lobe.
