Which lobes receive the two visual processing streams from the primary visual cortex?

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

Answer: (D)

From the primary visual cortex, information splits into two pathways. The dorsal stream carries spatial and motion information to the parietal lobe, supporting “where” and “how” tasks. The ventral stream carries form, color, and object identity to the temporal lobe, supporting “what” recognition. So the two lobes that receive these visual processing streams are the parietal and temporal lobes. The frontal lobe isn’t the destination of these streams, and the occipital lobe houses the primary visual cortex where the processing begins rather than where both streams terminate.
