Sometimes for medical reasons the brain is essentially split in two. The brain has 2 hemispheres which are near duplicates, with nerves carrying information between. When the brain is split in two, the individual acts almost like 2 people.
Each hemisphere controls one side of the body. If one half's eye is covered, and it is trying to pick up an object, it will fail. If the other half of the brain can see the object, then it pushes the oher half's hand aside and picks up the object. This doesn't disturb split brained people at all.
Does this mean we are two seperate people working together?
