Final answer:
Association fibers link areas within a cerebral hemisphere. These fibers are crucial for intrahemispheric communication, unlike the corpus callosum, which connects the two hemispheres.
Step-by-step explanation:
The type of nerve fibers that link areas within a cerebral hemisphere are known as association fibers. These fibers enable different parts of the hemisphere to communicate with each other and facilitate the integration of spatial, motor, sensory, and other information processed by the cerebral hemisphere. It is important to note that the corpus callosum is a different structure, which consists of a thick band of about 200 million axons that connects the left and right hemispheres allowing them to communicate. This function is different from that of association fibers, as the corpus callosum primarily facilitates communication between the hemispheres, not within the same hemisphere.
