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 great facility for explaining tricky scientific concepts in language that is engaging to all readers. She presents the basics of contemporary thought on consciousness as they relate to her own theory involving 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, as well as the work of philosophers such as John Searle and Daniel Dennett, she makes her case compellingly but gently, allowing 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? Whether or not the idea withstands time and testing, it is intriguing and thought-provoking, making The Private Life of the Brain
essential reading for minds seeking self-enlightenment. --Rob Lightner
From the Inside Flap
How do our unique personalities emerge from our anatomically identical physical brains? What gives rise to our emotions? Why do some drugs make us ecstatic while others make us miserable? For centuries, the most elusive and tantalizing questions about how the human mind works were left to the esoteric realm of philosophers. But in the last decade, there has finally been an explosion of interest from those who study the physical brain. In this groundbreaking scientific exploration, internationally acclaimed neuroscientist and author Susan Greenfield demystifies the private life of the brain. Embarking on an excursion deep inside the human brain, Greenfield takes us beyond the intricate tangle of cells, electrical impulses, and molecules to examine the physical basis of our emotions and search for the answer to one of the most enduring mysteries in modern science: How is a unique, subjective experience generated in each one of us? Informed by years of cutting–edge research, as well as compelling personal anecdotes that we can all relate to, Greenfield reveals that emotions, triggered by individual life experiences, are the very foundation upon which our brains build our unique minds. Offering us a brain scientist’s perspective on the intricate dance of emotions and cognitive abilities, Greenfield asserts that this extraordinary sense of the self is inextricably bound to the often mercurial world of emotions. Rich in insights from such diverse realms as neuroscience, pharmacology, psychology, philosophy, and everyday life, The Private Life of the Brain traces the life of our mind and reveals how our childhood experiences; intense emotions like fear, depression, and euphoria; and the drugs that induce these extreme feelings dramatically affect who we are. She argues that emotions exist at the core of our selves to a greater or lesser degree, depending on how much we are using or losing our mind at any given moment. Timely and provocative, The Private Life of the Brain is a tour de force that provides an eye–opening look through the authoritative lens of neuroscience. Captivating for novices and experts alike, this intriguing book presents an enlightening journey into the human brain for anyone who has ever pondered the mystery of who we are and how the brain works.
