    It’s not even one brain, it’s two chunks that function as one whole. Patients who have had a corpus callostomy (splitting the membrane connecting the hemispheres) can find one of their limbs going against what you’re trying to do.

    If you’re getting dressed, for example, your left side may refuse if it doesn’t like what you’re wearing. It can do totally random things and sometimes people have to use their controlled hand to physically restrain the other.

    They think the left half of the brain is responsible for speech and communication, so the right remains this silent observer under the thumb of the left when the connection is intact.

    But it has its own will, even if you don’t know it.
