Smarter Brains

Our abilities to reason, solve problems, and adapt to changing situations are part of what makes us human. But how is intelligence acquired and can it be improved? Peter Coyote narrates this PBS-aired documentary from filmmaker Jim Hoppin that examines the most complex and mysterious organ in the human body. Different parts of the brain carry out various functions, ranging from handling the most primitive of activities, to using language, reasoning, and memory (at any given time, billions of neurons are communicating in a process called "neuronal chatter"). Contrary to earlier beliefs, new scientific evidence shows that the human brain is always evolving, and can be improved at any age. Scientists are busy with a fresh initiative called the "Human Brain Project," using computers to map the brain in order to find out more about how it works and why it breaks down. Like cardiovascular exercise for the body, brains also need to stay in shape so that people can "be as smart as you can be at any age." Some ways to keep the brain healthy include physical exercise, "active experiencing," and meeting new challenges (whether it be acting, dancing, or learning sign language), or just getting out to meet others, and trading memories and perceptions. Offering a solid mix of information and encouragement, this guide to understanding and nurturing the brain is recommended. Aud: H, C, P. (S. Rees)
