A ground-breaking interdisciplinary study about conceptual origins linking hominid thinking with hominid evolution.

An examination of the stunning beauty of the brain's cellular form, with many color illustrations, and a provocative claim about the mind-brain relationship. The human brain is often described as the most complex object in the universe. Tens of billions of nerve cells-tiny tree-like structures—make up a massive network with enormous computational power. In this book, Giorgio Ascoli reveals another aspect of the human brain: the stunning beauty of its cellular form. Doing so, he makes a provocative claim about the mind-brain relationship. If each nerve cell enlarged a thousandfold looks like a tree, then a small region of the nervous system at the same magnified scale resembles a gigantic, fantastic forest. This structural majesty—illustrated throughout the book with extraordinary color images—hides the secrets behind the genesis of our mental states. Ascoli proposes that some of the most intriguing mysteries of the mind can be solved using the basic architectural principles of the brain. After an overview of the scientific and philosophical foundations of his argument, Ascoli links mental states with patterns of electrical activity in nerve cells, presents an emerging minority opinion of how the brain learns from experience, and unveils a radically new hypothesis of the mechanism determining what is learned, what isn't, and why. Finally, considering these notions in the context of the cosmic diversity within and among brains, Ascoli offers a new perspective on the roots of individuality and humanity.

Like 75% of American women, Ronnie Citron-Fink dyed her hair, visiting the salon every few weeks to hide gray roots in her signature dark brown mane. She wanted to look attractive, professional, young. Yet as a journalist covering health and the environment, she knew something wasn’t right. All those unpronounceable chemical names on the back of the hair dye box were far from natural. Were her recurring headaches and allergies telltale signs that the dye offered the illusion of health, all the while undermining it? So after twenty-five years of coloring, Ronnie took a leap and decided to ditch the dye. Suddenly everyone, from friends and family to rank strangers, seemed to have questions about her hair. How’d you do it? Are you doing that on purpose? Are you OK? Armed with a mantra that explained her reasons for going gray—the upkeep, the cost, the chemicals—Ronnie started to ask her own questions. What are the risks of coloring? Why are hair dye companies allowed to use chemicals that may be harmful? Are there safer alternatives? Maybe most importantly, why do women feel compelled to color? Will I still feel like me when I have gray hair? True Roots follows Ronnie’s journey from dark dyes to a silver crown of glory, from fear of aging to embracing natural beauty. Along the way, readers will learn how to protect themselves, whether by transitioning to their natural color or switching to safer products. Like Ronnie, women of all ages can discover their own hair story, one built on individuality, health, and truth.

Discover the Other 90% of Your Brain Learn about brain science breakthroughs that might hold the key to intelligence, creativity, and imagination. Discover amazing cells that keep your brain growing, adapting, and healing. Preview possible breakthroughs for brain cancer, brain trauma, Alzheimer's, Parkinson's, and even schizophrenia. If you know anything about brains, you've heard of neurons. Those are the cells that have long been seen as central to virtually everything your brain thinks, feels, and does. But neurons represent only 10% of your brain cells. What does the other 90% do? Until recently, scientists didn't have a clue. Now, they're discovering the real function of those long-neglected glial cells-and the story is nothing short of amazing. In "The Root of Thought," brain scientist Andrew Koob reveals that story. You'll learn what glial cells are, how they function, and how they might help explain everything from intelligence and creativity to imagination and dreams. Then, Koob reveals the tantalizing clues about glial cells that could eventually lead to cures for brain injury, psychiatric disorders, Alzheimer's, Parkinson's, Lou Gehrig's disease, and even brain cancer.

The topic of the origins of theatre is one of the most controversial in theatre studies, with a long history of heated discussions and strongly held positions. In The Roots of Theatre, Eli Rozik enters the debate in a feisty way, offering not just another challenge to those who place theatre’s origins in ritual and religion but also an alternative theory of roots based on the cultural and psychological conditions that made the advent of theatre possible. Rozik grounds his study in a comprehensive review and criticism of each of the leading historical and anthropological theories. He believes that the quest for origins is essentially misleading because it does not provide any significant insight for our understanding of theatre. Instead, he argues that theatre, like music or dance, is a sui generis kind of human creativity—a form of thinking and communication whose roots lie in the spontaneous image-making faculty of the human psyche. Rozik’s broad approach to research lies within the boundaries of structuralism and semiotics, but he also utilizes additional disciplines such as psychoanalysis, neurology, sociology, play and game theory, science of religion, mythology, poetics, philosophy of language, and linguistics. In seeking the roots of theatre, what he ultimately defines is something substantial about the nature of creative thought—a rudimentary system of imagistic thinking and communication that lies in the set of biological, primitive, and infantile phenomena such as daydreaming, imaginative play, children’s drawing, imitation, mockery (caricature, parody), storytelling, and mythmaking.

Essays that explore quirky, counterintuitive aspects of brain function and “make us realize that what goes on in our minds is nothing short of magical” (Scientific American). Neuroscientist David J. Linden approached leading brain researchers and asked each the same question: “What idea about brain function would you most like to explain to the world?” Their responses make up this one-of-a-kind collection of popular science essays that seeks to expand our knowledge of the human mind and its possibilities. The contributors, whose areas of expertise include human behavior, molecular genetics, evolutionary biology, and comparative anatomy, address a host of fascinating topics ranging from personality to perception, to learning, to beauty, to love and sex. The manner in which individual experiences can dramatically change our brains’ makeup is explored. Professor Linden and his contributors open a new window onto the landscape of the human mind and into the cutting-edge world of neuroscience with a fascinating, enlightening compilation that science enthusiasts and professionals alike will find accessible and enjoyable. “Scientists who can effectively communicate science are rare, but here are forty of the best, describing with clarity and enthusiasm the latest in brain research and its impact on our lives.” —Gordon M. Shepherd, co-editor of Handbook of Brain Microcircuits

The cognitive science of religion is a new discipline that looks at the roots of religious belief in the cognitive architecture of the human mind. The Roots of Religion deals with the philosophical and theological implications of the cognitive science of religion which grounds religious belief in human cognitive structures: religious belief is ’natural’, in a way that even scientific thought is not. Does this new discipline support religious belief, undermine it, or is it, despite many claims, perhaps eventually neutral? This subject is of immense importance, particularly given the rise of the ’new atheism’. Philosophers and theologians from North America, UK and Australia, explore the alleged conflict between truth claims and examine the roots of religion in human nature. Is it less ’natural’ to be an atheist than to believe in God, or gods? On the other hand, if we can explain theism psychologically, have we explained it away. Can it still claim any truth? This book debates these and related issues.

National Book Award Finalist: “This man’s ideas may be the most influential, not to say controversial, of the second half of the twentieth century.”—Columbus Dispatch At the heart of this classic, seminal book is Julian Jaynes's still-controversial thesis that human consciousness did not begin far back in animal evolution but instead is a learned process that came about only three thousand years ago and is still developing. The implications of this revolutionary scientific paradigm extend into virtually every aspect of our psychology, our history and culture, our religion—and indeed our future. “Don’t be put off by the academic title of Julian Jaynes’s The Origin of Consciousness in the Breakdown of the Bicameral Mind. Its prose is always lucid and often lyrical…he unfolds his case with the utmost intellectual rigor.”—The New York Times “When Julian Jaynes . . . speculates that until late in the twentieth millennium BC men had no consciousness but were automatically obeying the voices of the gods, we are astounded but compelled to follow this remarkable thesis.”—John Updike, The New Yorker “He is as startling as Freud was in The Interpretation of Dreams, and Jaynes is equally as adept at forcing a new view of known human behavior.”—American Journal of Psychiatry
