Final answer:
Commissural fibers do not form the corpus striatum as it is composed of the caudate nucleus and the putamen. The corpus striatum is involved in the control of movement, while commissural fibers allow for communication between the left and right cerebral hemispheres.
Step-by-step explanation:
Commissural fibers do not form the corpus striatum. The corpus striatum is composed of two structures: the caudate nucleus and the putamen. These structures are primarily involved in the control of movement and are part of the basal ganglia. Commissural fibers, on the other hand, connect corresponding areas in the left and right cerebral hemispheres, allowing for communication between the two.
For example, one major commissural fiber bundle is the corpus callosum, which connects various regions of the cerebral cortex. So, the correct answer to the question is 2) False.
