The idea that one can transplant a brain and thus a human's consciousness is based on erroneous concepts. Because humans currently have only physical senses they assume, naturally, that all of reality is based on matter. The situation however is that the brain just mirrors the reality of consciousness. Therefore the brain is not the center of consciousness, but only reflects the activities of mind. Just as looking in a mirror you see a reflection of a person which is not the reality of the person but only a reflection of something that is real, so seeing the activity of the brain is only the reflection of the activity of mind.
