A)to guide migrating neurons in the prenatal brain to destinations in the opposite hemisphere

Question

Quizplus · Accepted Answer

The corpus callosum is a bundle of nerve fibers that connects the two hemispheres of the brain. One of its proposed functions is to allow each hemisphere to inhibit the activity of the other, which helps to prevent both sides of the brain from carrying out conflicting actions or sending conflicting signals. Option A is incorrect because the corpus callosum does not guide migrating neurons in the prenatal brain, but rather connects the neurons that have already migrated to the two hemispheres. Option C is also incorrect because while the corpus callosum does provide some structural support for the cortex, this is not its primary function. Option D is incorrect because there are proposed functions of the corpus callosum, as described above.
