Final answer:
The parietal lobe of the human brain has expanded in the superior region. Comparing human and monkey parietal lobes is difficult due to the major differences in brain structure and function caused by the expansion.
Step-by-step explanation:
The parietal lobe of the human brain has undergone major expansion in the superior region, which is above the lateral sulcus.
Comparing the parietal regions of the human brain to those of monkeys is difficult because the expansion of the parietal lobe in humans has resulted in significant differences in brain structure and function. Monkeys have a smaller parietal lobe compared to humans, which affects their ability to perform certain cognitive tasks and exhibit complex behaviors.
