How can a physical brain create our experience of the world? What creates our identity? Do we really have free will? Could consciousness itself be an illusion? Exciting new developments in brain science are opening up debates on these issues, and the field has now expanded to include biologists, neuroscientists, psychologists, and philosophers.

Topics include vision and attention, theories of self and will, experiments on action and awareness, altered states of consciousness, and the effects of brain damage and drugs.
