We asked
Patricia Landry, M.D. She wrote: “It is true that each side
of the brain controls the opposite side of the body. The
brain is set up to do this. The brain cells that control
movement are formed into pathways, like telephone wires,
which cross over one another to the opposite side of the
body. That may sound like a mixed-up system. But by crossing
over, the pathways let the two sides of the brain share the
information they need to make the two sides of the body work
together.”
