The two visual processing streams originate from which brain region?

• A. Primary visual cortex.
• B. Cerebellum.
• C. Primary auditory cortex.
• D. Prefrontal cortex.

Answer: (A)

The two visual processing streams originate from the primary visual cortex (V1) in the occipital lobe. After initial feature processing in V1, visual information splits into the dorsal pathway, which analyzes spatial location and motion, and the ventral pathway, which identifies objects and their attributes. The other areas listed don’t serve as the source of these streams: the cerebellum coordinates movement, the primary auditory cortex processes hearing, and the prefrontal cortex handles higher-order cognition. So, the origin is the primary visual cortex.
