Which statement best describes the destinations of the two visual processing streams?

• A. The dorsal stream projects to the frontal lobe and the ventral stream to the occipital lobe.
• B. One stream goes to the parietal lobe and the other to the temporal lobe.
• C. Both streams travel to the brainstem.
• D. The streams originate in the retina and bypass the cortex.

Answer: (B)

Two visual processing streams diverge after the early visual cortex, with one stream projecting to the parietal lobe and the other to the temporal lobe. This layout underpins their distinct roles: the dorsal stream supports spatial processing and visually guided actions, while the ventral stream supports object recognition and identity. The other statements don’t fit because they misstate the cortical targets (frontal or brainstem) or imply the streams bypass the cortex, which they do not.
