A brilliant new theory of the mind that upends our understanding of how the brain interacts with the world “This thoroughly readable book will convince you that the brain and the world are partners in constructing our understanding.” —Sean Carroll, New York Times bestselling author of The Biggest Ideas in the Universe: Space, Time, and Motion For as long as we’ve studied human cognition, we’ve believed that our senses give us direct access to the world. What we see is what’s really there—or so the thinking goes. But new discoveries in neuroscience and psychology have turned this assumption on its head. What if rather than perceiving reality passively, your mind actively predicts it? Widely acclaimed philosopher and cognitive scientist Andy Clark unpacks this provocative new theory that the brain is a powerful, dynamic prediction engine, mediating our experience of both body and world. From the most mundane experiences to the most sublime, reality as we know it is the complex synthesis of sensory information and expectation. Exploring its fascinating mechanics and remarkable implications for our lives, mental health, and society, Clark nimbly illustrates how the predictive brain sculpts all human experience. Chronic pain and mental illness are shown to involve subtle malfunctions of our unconscious predictions, pointing the way towards more effective, targeted treatments. Under renewed scrutiny, the very boundary between ourselves and the outside world dissolves, showing that we are as entangled with our environments as we are with our onboard memories, thoughts, and feelings. And perception itself is revealed to be something of a controlled hallucination. Unveiling the extraordinary explanatory power of the predictive brain, The Experience Machine is a mesmerizing window onto one of the most significant developments in our understanding of the mind.

Neuroscientist V.S. Ramachandran is internationally renowned for uncovering answers to the deep and quirky questions of human nature that few scientists have dared to address. His bold insights about the brain are matched only by the stunning simplicity of his experiments -- using such low-tech tools as cotton swabs, glasses of water and dime-store mirrors. In Phantoms in the Brain, Dr. Ramachandran recounts how his work with patients who have bizarre neurological disorders has shed new light on the deep architecture of the brain, and what these findings tell us about who we are, how we construct our body image, why we laugh or become depressed, why we may believe in God, how we make decisions, deceive ourselves and dream, perhaps even why we're so clever at philosophy, music and art. Some of his most notable cases: A woman paralyzed on the left side of her body who believes she is lifting a tray of drinks with both hands offers a unique opportunity to test Freud's theory of denial. A man who insists he is talking with God challenges us to ask: Could we be "wired" for religious experience? A woman who hallucinates cartoon characters illustrates how, in a sense, we are all hallucinating, all the time. Dr. Ramachandran's inspired medical detective work pushes the boundaries of medicine's last great frontier -- the human mind -- yielding new and provocative insights into the "big questions" about consciousness and the self.

Why language ability remains resilient and how it shapes our lives. We acquire our native language, seemingly without effort, in infancy and early childhood. Language is our constant companion throughout our lifetime, even as we age. Indeed, compared with other aspects of cognition, language seems to be fairly resilient through the process of aging. In Changing Minds, Roger Kreuz and Richard Roberts examine how aging affects language—and how language affects aging. Kreuz and Roberts report that what appear to be changes in an older person's language ability are actually produced by declines in such other cognitive processes as memory and perception. Some language abilities, including vocabulary size and writing ability, may even improve with age. And certain language activities—including reading fiction and engaging in conversation—may even help us live fuller and healthier lives. Kreuz and Roberts explain the cognitive processes underlying our language ability, exploring in particular how changes in these processes lead to changes in listening, speaking, reading, and writing. They consider, among other things, the inability to produce a word that's on the tip of your tongue—and suggest that the increasing incidence of this with age may be the result of a surfeit of world knowledge. For example, older people can be better storytellers, and (something to remember at a family reunion) their perceived tendency toward off-topic verbosity may actually reflect communicative goals.

This Research Topic is part of the article collection series: Towards an Understanding of Tinnitus Heterogeneity. Tinnitus is the perception of a sound when no external sound is present. The severity of tinnitus varies but it can be debilitating for many patients. With more than 100 million people with chronic tinnitus worldwide, tinnitus is a disorder of high prevalence.
