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.
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?
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.
