Imagination isn't the exception in our daily lives; it's our default setting

Imagination is about far more than whether people think of themselves as creative or not. We use our imagination all the time in planning, anticipating, daydreaming, reminiscing and being able to enjoy other people's stories. In fact, we don't live in the here and now as much as we might think. Imagination isn't the exception to our daily lives; it's our default setting.From hallucinations to sleepwalking, from REM sleep to delusions, neurologist Adam Zeman brilliantly guides us through the latest scientific discoveries in the world of the imagination. Imagine looking at a cube and your eye will trace the contours of the cube as if you were actually seeing it. Imagine inhaling and the airflow through your nose will increase. In grief, you might imagine that you saw your loved one again - and be consoled by the experience. And yet some people have no visual imagination at all - they would even be unable to picture their family if asked to - but still lead fulfilling, even highly creative, lives.From how infants perceive the world to how we can anticipate the thoughts of other people, from the benefits of play to mental disorders, The Shape of Things Unseen dazzles and delights in its insights into the workings of the human mind.

Presents the stories of patients with a variety of neurological disorders, some familiar (epilepsy, chronic fatigue, stroke, memory loss) and others relatively mysterious. This title reveals the various levels of the brain, from the atom to the mind, and explores what happens when workings at each level go awry.

This engaging and readable book provides an introduction to consciousness that does justice both to the science and to the philosophy of consciousness, that is, the mechanics of the mind and the experience of awareness. The book opens with a general discussion of the brain and of consciousness itself. Then, exploring the areas of brain science most likely to illuminate the basis of awareness, Zeman focuses on the science of sleep and waking and on the science of vision. He describes healthy states and disordersepilepsy, narcolepsy, blindsight and hallucinations after strokethat provide insights into the capacity for consciousness and into its contents. And he tracks the evolution of the brain, the human species, and human culture and surveys the main current scientific theories of awareness, pioneering attempts to explain how the brain gives rise to experience.Zeman concludes by examining philosophical arguments about the nature of consciousness. A practicing neurologist, he animates his text with examples from the behavioral and neurological disorders of his patients and from the expanding mental worlds of young children, including his own. His book is an accessible and enlightening explanation of why we are conscious.
