Neural control of bimanual movement

How is neural activity in motor cortex coordinated between the two hemispheres?

Each hemisphere primarily controls muscles on the opposite side of the body. Yet the two sides of the body must often be coordinated. We ask what role motor cortex plays in this process. How active is motor cortex when the 'wrong' side of the body moves? If active, is it active in the same way? How does activity change when both sides move together?
