Theories of consciousness are challenged by recent research into the impact of brain function on the sense of self.
There may be no single answer to what consciousness is, but we may still be able to find ways to explain what is going on in the brain. This would help resolve why our conscious experience takes the shape and form it does, and elucidate what happens to consciousness when one of the interacting systems that make possible the self-knowing mind breaks down. These phenomena provide vital clues about the neural correlates of consciousness and are a step on the road to understanding why things work as they do.
Getting at the elusive nature of our own experience and freeing ourselves from faulty interpretations is a tricky business. Many disciplines are needed if we are to make a real breakthrough.
