Final answer:
The size of the Corpus Callosum correlates positively with the ability of the two hemispheres of the brain to communicate with each other.
Step-by-step explanation:
The size of the Corpus Callosum correlates positively with the ability of the two hemispheres of the brain to communicate with each other. A larger Corpus Callosum means more neural fibers and thus more efficient communication between the hemispheres. For example, people with a sectioned Corpus Callosum may have difficulty performing tasks that require both hemispheres to work together, such as coordinating movements with both hands.
