Which area in the occipital lobe is involved in visual processing and contains the primary visual cortex?

• A. Primary auditory cortex
• B. Somatosensory cortex
• C. Prefrontal cortex
• D. Primary visual cortex (V1)

Answer: (D)

Visual information first arrives in the occipital lobe at the primary visual cortex, V1, which is the initial cortical site for processing vision. This area receives input from the retina via the thalamus and begins encoding basic features like edges and orientation before higher visual areas handle more complex processing. The other options belong to different sensory systems or brain regions—primary auditory cortex is in the temporal lobe and handles sound, somatosensory cortex is in the parietal lobe and processes touch, and the prefrontal cortex is in the frontal lobe and supports higher cognitive functions. So, the area in the occipital lobe that contains the primary visual cortex is the primary visual cortex itself (V1).
