The Meaning of Consciousness

When the brain changes, your consciousness changes. Even a very tiny change in the brain makes a giant difference to your conscious experience. One of my mentors, the late Francis Crick, had a chalkboard in his office and it was busy with lots of scribbles. But there was one word right in the center and that was meaning. Why do you care about anything? How do you run a bunch of activity through cells and get meaning? This is really the question of consciousness.
