Acclaimed neuroscientist Gary Wenk reveals the fascinating impacts of exercise on the brain Decades of research demonstrate that regular modest levels of exercise improve heart and lung function and may relieve joint pain. Regular daily exercise will help your body to regulate blood sugar levels and reduce inflammation, and many of these benefits are a consequence of reducing the amount of body fat you carry around. Your body clearly benefits in many ways from regular exercise. Does your brain benefit as well? Does regular exercise positively affect brain function? Does our thinking become faster because we exercise? Does running a marathon make us smarter? Dr. Gary Wenk's goal is to provide a realistic perspective on what benefits your brain should expect to achieve from exercise. Your Brain on Exercise skillfully blends scholarship with illuminating insights and clarity. Without requiring any specialized knowledge about the brain, Your Brain on Exercise entertainingly illustrates the intersection between brain health, the consequences of exercise, and our need to eat in an entirely new light. An internationally renowned neuroscientist and medical researcher, Dr. Wenk has been educating college and medical students about the brain and lecturing around the world for more than forty years.

What is the principle purpose of a brain? A simple question, but the answer has taken millennia for us to begin to understand. So critical for our everyday existence, the brain still remains somewhat a mystery. Gary L. Wenk takes us on a tour of what we do know about this enigmatic organ, showing us how the workings of the human brain produce our thoughts, feelings, and fears, and answering questions such as: How did humans evolve such a big brain? What is an emotion and why do we have them? What is a memory and why do we forget so easily? How does your diet affect how you think and feel? What happens when your brain gets old? Throughout human history, ignorance about the brain has caused numerous non-scientific, sometimes harmful, interventions to be devised based on interpretations of scientific facts that were misguided. Wenk discusses why these neuroscientific myths are so popular, and why some of the interventions based on them are a waste of time and money. With illuminating insights, gentle humor, and welcome simplicity, The Brain: What Everyone Needs to Know makes the complex biology of our brains accessible to the general reader.

Optik, Laser, Wellenleiter stellt eine Einfuhrung in die angewandte Optik dar. Dabei werden nicht nur Strahlenoptik mit optischen Instrumenten, Lichtquellen und Detektoren einerseits sowie Wellenoptik mit Interferometrie andererseits behandelt; es wird auch ausfuhrlich auf Holographie, Laser, Koharenz, Faseroptik, Wellenleiter und integrierte Optik eingegangen. Die physikalischen Grundlagen, Anwendungen und die Instrumentierung stehen dabei stets im Vordergrund. Mehr als 100 Ubungen dienen der Vertiefung des Stoffes. Das Buch ist sowohl als vorlesungsbegleitende Lekture fur Studenten als auch als Nachschlagewerk fur Diplomanden, Wissenschaftler und Praktiker geeignet."

An internationally renowned neuroscientist, Dr. Wenk has been educating college and medical students about the brain and lecturing around the world for more than forty years. He has published over three hundred publications on the effects of drugs upon the brain. This essential book vividly demonstrates how a little knowledge about the foods and drugs we eat can teach us a lot about how our brain functions. The information is presented in an irreverent and non-judgmental manner that makes it highly accessible to high school teenagers, inquisitive college students and worried parents. Dr. Wenk has skillfully blended the highest scholarly standards with illuminating insights, gentle humor and welcome simplicity. The intersection between brain science, drugs, food and our cultural and religious traditions is plainly illustrated in an entirely new light. Wenk tackles fundamental questions, including: * Why do you wake up tired from a good long sleep and why does your sleepy brain crave coffee and donuts? * How can understanding a voodoo curse explain why it is so hard to stop smoking? * Why is a vegetarian or gluten-free diet not always the healthier option for the brain? * How can liposuction improve brain function? * What is the connection between nature's hallucinogens and religiosity? * Why does marijuana impair your memory now but protect your memory later in life? * Why do some foods produce nightmares? * What are the effects of diet and obesity upon the brains of infants and children? * Are some foods better to eat after traumatic brain injury?
