We are on the brink of understanding ancient mysteries: how we know, what governs our nature, what makes a person different from a thing. In the last decade, more than twenty disciplines dealing with every aspect of the brain have contributed to a revolution in the neurosciences--a revolution as significant, in the view of many observers, as the Galilean and Copernican revolutions in mathematics and physics or the Darwinian revolution in biology. In this book, one of the world's foremost brain scientists gives us a glimpse into the workings of the human brain--the most complex material object in the universe. A match head's worth of the brain contains about a billion connections that can combine in ways which can only be described as hyperastronomical--on the order of ten followed by millions of zeros (there are only about ten followed by eighty zeros' worth of positively charged particles in the whole known universe).^

In A Universe of Consciousness, Gerald Edelman builds on the radical ideas he introduced in his monumental trilogy-Neural Darwinism, Topobiology, and The Remembered Present-to present for the first time an empirically supported full-scale theory of consciousness. He and the neurobiolgist Giulio Tononi show how they use ingenious technology to detect the most minute brain currents and to identify the specific brain waves that correlate with particular conscious experiences. The results of this pioneering work challenge the conventional wisdom about consciousness.
