And of course, there's occasionalism, which holds that the mind and the body (Including the brain) match up without the mind actually having a causal influence on the body at all. I don't think this removes responsibility for actions though, because even if this is true, whatever we choose to do is still what our bodies do,so we can still choose our actions. Like how two superrational players of the prisoners dilemma can choose the action of their coplayer by choosing their own action.
