In ''Magic Trees of the Mind,'' pioneer brain researcher Dr. Marian Diamond and top science journalist Janet Hopson take us through the evolutionary journey of a child's brain, showing how our minds are stimulated in specific ways at every age. This mental stimulation produces prolifically branching neurons - The ''magic trees of the mind'' - which are capable of processing ever greater amounts of information as they grow. Under nature's own code of ''use it or lose it, '' a child who experiences appropriate stimulation gains the increased capacity to develop his or her full potential, and is set on the path of lifelong learning. Based on interviews with noted scientists in the field and original surveys of thousands of parents and children, here are detailed analyses of cutting-edge programs designed to develop and expand your child's mind, including prenatal stimulation and enrichment ideas for babies, toddlers, preschoolers, grade school children, and teenagers. Complete with a comprehensive resource guide of related books, products, organizations, websites, and learning centers, ''Magic Trees of the Mind'' renews our birthright to ''think, learn and create, '' with the encouraging news that, although there are critical periods for learning, it's never too late to plant another tree.
