Which lobe is primarily responsible for visual processing?

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

Answer: (D)

Visual processing begins in the occipital lobe, which sits at the back of the brain. Its primary visual cortex receives signals from the eyes (via the thalamus) and starts decoding basic features like light, color, edges, and motion. This initial processing happens here before information is sent to other areas for more complex analysis. Other lobes contribute to related functions—frontal for planning, parietal for spatial processing, temporal for memory and recognition—but the occipital lobe is the main region responsible for visual input and its initial interpretation.
