Which lobe processes visual information?

Which lobe processes visual information?

• A. Frontal lobe
• B. Parietal lobe
• C. Temporal lobe
• D. Occipital lobe

Answer: (D)

Processing visual information happens mainly in the occipital lobe, which sits at the back of the brain. The primary visual cortex in this lobe receives signals from the retina via the optic nerve, optic chiasm, optic tract, and the lateral geniculate nucleus of the thalamus, and it analyzes basic features like edges, color, and motion. From there, higher visual processing continues within the occipital lobe to help recognize shapes and objects. Other lobes contribute to related functions—frontal for planning and voluntary movement, parietal for touch and spatial awareness, temporal for hearing and memory—but the initial and central processing of visual input occurs in the occipital lobe.
