What is happening in the brain when we drink too much alcohol, get high on ecstasy or experience road rage? Emotion, says internationally acclaimed neuroscientist Susan Greenfield, is the building block of consciousness. As our minds develop we create a personalized inner world based on our experiences. But during periods of intense emotion, such as anger, fear or euphoria, we can literally lose our mind, returning to the mental state we experienced as infants. Challenging many preconceived notions, Susan Greenfield's groundbreaking book seeks to answer one of science's most enduring mysteries: how our unique sense of self is created.

What's going on in there? One of the great scientific and philosophical mysteries is how a few pounds of wet, salty cobwebs can give rise to the rich experience that we call consciousness. Oxford neuroscientist Susan Greenfield peers inside the dimly lit skull to show us what she thinks is going on in The Private Life of the Brain. Greenfield has a facility for explaining tricky scientific concepts in language that can engage any reader. She presents the basics of contemporary thought on consciousness as they relate to her own theory, which involves a continuum of experience between sensual, emotional grounding in the surrounding world and rational, cognitive withdrawal into mental life. Arguing from a wide range of animal and human research, and drawing on the work of philosophers John Searle and Daniel Dennett, she makes her case compellingly but gently, granting that other theories might also hold in this still-uncharted territory. Looking in depth at depression, drug use, and fear, Greenfield shows how each is explained by her continuum theory and how each relates to the life of the human organism as a whole. Could it be true that as our minds work harder, our hearts lose some feeling, and vice versa? It's an intriguing, thought-provoking idea, one that alone makes The Private Life of the Brain essential reading for minds seeking self-enlightenment. --Rob Lightner
