Detailed explanation-1: -The commissural fibers or transverse fibers are axons that connect the two hemispheres of the brain. In contrast to commissural fibers, association fibers connect regions within the same hemisphere of the brain, and projection fibers connect each region to other parts of the brain or to the spinal cord.
Detailed explanation-2: -The corpus callosum is the main and largest of the commisural pathways that connects the right and left cerebral hemispheres.
Detailed explanation-3: -Commissural fibers connect an area in one hemisphere with an area in the opposite hemisphere. The corpus callosum is the largest set of commissural fibers in the brain and is a pathway of crucial importance to speech-language functions (Fig. 2-10, B).
