Several months after split-brain surgery, the number of incidents of conflicts between the two hemispheres diminishes because ____.
A) portions of the corpus callosum grow back
B) the right hemisphere begins to control all body muscles
C) the hemispheres learn ways of cooperating with each other
D) the cerebellum assumes the former functions of the corpus callosum

Question

Quizplus · Accepted Answer

After split-brain surgery, the two hemispheres of the brain are essentially disconnected from each other because the corpus callosum, which allows for communication between the hemispheres, has been severed. This can result in conflicts and confusion as each hemisphere tries to control the body independently. However, over time the hemispheres can learn to cooperate with each other, reducing the frequency of conflicts. Although portions of the corpus callosum may eventually grow back, this process can take months or even years and is not the main reason why conflicts diminish. The right hemisphere does not typically take over control of all body muscles after split-brain surgery, and the cerebellum's functions are not the same as the corpus callosum's.
