ABSTRACT
This chapter provides answers for the following questions: How is it possible for split-brain patients with two independent minds to live a relatively normal life, even to the extent that their condition is not obvious during a standard medical examination? If split-brain patients have independent minds in each half of their brain, can those minds disagree? If there are two minds—one in each hemisphere—in people whose link between the two halves of the brain has been cut, does this mean that there are two minds in those of us with intact brains? In experiments on split-brain patients, care is taken to ensure that objects are only visible to one half of the brain. In real life, however, such individuals can move their eyes and their head so that both hemispheres receive the same visual input. In the majority of cases if both minds receive the same visual information in the same circumstances then they will both choose the same response.
