Occipital lobe processes visual information.

Occipital lobe processes visual information.

• A. A region that processes language
• B. A region that processes visual information
• C. A region that processes touch
• D. A region involved in smell

Answer: (B)

Visual information processing is localized in the occipital lobe, which contains the primary visual cortex. Signals from the retina travel via the optic nerves and tracts to the lateral geniculate nucleus of the thalamus and then to the occipital lobe. There, basic features such as edges, contrast, and color are detected, and higher-level interpretation proceeds through dorsal and ventral streams to the parietal and temporal lobes for motion and object recognition. This makes the occipital lobe the region responsible for vision, unlike the areas handling language, touch, or smell in other parts of the brain.
