Which cortical region processes vision?

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

Answer: (B)

Vision is processed mainly in the occipital cortex, which houses the primary visual cortex (V1) at the back of the brain. This region receives input from the retina via the lateral geniculate nucleus of the thalamus and begins decoding basic visual information such as edges, orientation, and light. From there, processing extends into extrastriate areas that handle more complex aspects of vision. While other lobes contribute to how we use vision—like the parietal lobe for spatial orientation and action guidance, or the temporal lobe for recognizing objects and faces—the initial and central processing of visual signals occurs in the occipital lobe.
