Which pair of brain lobes are the targets of the dorsal and ventral streams respectively?

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

Answer: (C)

Two major visual processing streams run from the occipital cortex to different cortical areas to handle different aspects of vision. The dorsal stream targets the parietal lobe and is associated with spatial location and guiding actions (“where/how”), while the ventral stream targets the temporal lobe and is tied to object recognition and identification (“what”). So the pair that fits the question is Parietal and Temporal, reflecting the dorsal stream’s endpoint in parietal cortex and the ventral stream’s endpoint in temporal cortex. Other options place endpoints in frontal or occipital areas, which aren’t the usual targets of these two streams.
