It is a subject of much research in philosophy of the mind, psychology, neurology, and cognitive science. This book presents a compilation of new and significant research on the many facets of consciousness. These include psychoenergetic studies, neurobiological hypothesis, theories on unconsciousness and psychoanalytic theories relating to sexual experiences.
