Question

Commissural fibers interconnect areas of cerebral cortex. They carry pain information to the correct brain structure. They are divided by the longitudinal fissure. They cross from one cerebral hemisphere to the other hemisphere. They link the cerebral cortex to the diencephalon. What is the function of commissural fibers?

1) Interconnect areas of cerebral cortex
2) Carry pain information to the correct brain structure
3) Are divided by the longitudinal fissure
4) Cross from one cerebral hemisphere to the other hemisphere
5) Link the cerebral cortex to the diencephalon

Answer 1

Commissural fibers, such as those in the corpus callosum, serve to interconnect areas of the cerebral cortex, enabling communication between the two hemispheres of the brain.

Step-by-step explanation:

The function of commissural fibers, specifically in the corpus callosum, is to interconnect areas of the cerebral cortex. These fibers allow the two hemispheres of the brain to communicate with each other by carrying messages back and forth. One of the main commissural fibers is the corpus callosum, which consists of a thick bundle of axons that lies deep within the brain, connecting each point in one cerebral hemisphere to the mirror-image point in the opposite hemisphere. This interhemispheric communication is vital for the coordination of various cognitive and motor functions.
