The brain is an extremely complicated organ, every part is essential for full function and potential. We map our brain in parts to where we have a rough estimate of what they do but it is shown that other areas can adapt to meet that function if the original area is damaged, it shows that we still do not fully understand ourselves, you would essentially be losing control and function to one side of your body by the way, this is what happens to patients suffering from extreem seizures getting half their brain removed, half of them removed, just to stop it.
