Experiments On Animal Electricity

Download or read book Shocking Frogs written by Marco Piccolino and published by Oxford University Press, USA. This book was released on 2013 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: "... and still we could never suppose that fortune were to be so friendly to us, such as to allow us to be perhaps the first in handling, as it were, the electricity concealed in nerves, in extracting it from nerves, and, in some way, in putting it under everyone's eyes." With these words, Luigi Galvani announced to the world in 1791 his discovery that nervous conduction and muscle excitation are electrical phenomena. The result of more than years of intense experimental work, Galvani's milestone achievement concluded a thousand-year scientific search, in a field long dominated by the antiquated beliefs of classical science. Besides laying the grounds for the development of the modern neurosciences, Galvani's discovery also brought to light an invention that would forever change humankind's everyday life: the electric battery of Alessandro Volta. In an accessible style, written for specialists and general readers alike, Shocking Frogs retraces the steps of both scientific discoveries, starting with the initial hypotheses of the Enlightenment on the involvement of electricity in life processes. So doing, it also reveals the inconsistency of the many stereotypes that an uncritical cultural tradition has imparted to the legacies of Galvani and Volta, and proposes a decidedly new image of these monumental figures.

Download or read book The Spark of Life: Electricity in the Human Body written by Frances Ashcroft and published by W. W. Norton & Company. This book was released on 2012-09-24 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This is a wonderful book. Frances Ashcroft has a rare gift for making difficult subjects accessible and fascinating." —Bill Bryson, author of The Body: A Guide for Occupants What happens during a heart attack? Can someone really die of fright? What is death, anyway? How does electroshock treatment affect the brain? What is consciousness? The answers to these questions lie in the electrical signals constantly traveling through our bodies, driving our thoughts, our movements, and even the beating of our hearts. The history of how scientists discovered the role of electricity in the human body is a colorful one, filled with extraordinary personalities, fierce debates, and brilliant experiments. Moreover, present-day research on electricity and ion channels has created one of the most exciting fields in science, shedding light on conditions ranging from diabetes and allergies to cystic fibrosis, migraines, and male infertility. With inimitable wit and a clear, fresh voice, award-winning researcher Frances Ashcroft weaves together compelling real-life stories with the latest scientific findings, giving us a spectacular account of the body electric.

Download or read book Spark from the Deep written by William J. Turkel and published by JHU Press. This book was released on 2013-09 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: How encounters with strongly electric fish informed our grasp of electricity. Spark from the Deep tells the story of how human beings came to understand and use electricity by studying the evolved mechanisms of strongly electric fish. These animals have the ability to shock potential prey or would-be predators with high-powered electrical discharges. William J. Turkel asks completely fresh questions about the evolutionary, environmental, and historical aspects of people’s interest in electric fish. Stimulated by painful encounters with electric catfish, torpedos, and electric eels, people learned to harness the power of electric shock for medical therapies and eventually developed technologies to store, transmit, and control electricity. Now we look to these fish as an inspiration for engineering new sensors, computer interfaces, autonomous undersea robots, and energy-efficient batteries.

Download or read book EXPLORE ELECTRICITY! written by Carmella Van Vleet and published by Nomad Press. This book was released on 2014-01-07 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the pace of how we harness and utilize electricity, as well as the importance of developing new sources of energy, electricity is a timely subject for kids to explore. In Explore Electricity! With 25 Great Projects, kids ages 6-9 will learn the basics of electricity: currents, circuits, power, magnetism and electromagnetism, motors and generators. They’ll become more attuned to how much they rely on electricity in their daily lives. They’ll also understand that while electricity is a wonderful resource, and one we’ve used to our advantage ever since it was discovered, the future of how we make and use electricity is still changing and there are things they can do today to impact these changes. This title invites kids to experiment on their own with 25 simple projects that will “spark” their learning and enthusiasm, including making their own clothespin switch, lemon battery, compass, electromagnet, and flashlight, as well as generating their own “lightning.” These hands-on activities combined with informational text will excite kids about STEM? the interrelated fields of science, technology, engineering, and mathematics.

Download or read book The Ten Most Beautiful Experiments written by George Johnson and published by Vintage. This book was released on 2009-03-10 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: A dazzling, irresistible collection of the ten most groundbreaking and beautiful experiments in scientific history. With the attention to detail of a historian and the storytelling ability of a novelist, New York Times science writer George Johnson celebrates these groundbreaking experiments and re-creates a time when the world seemed filled with mysterious forces and scientists were in awe of light, electricity, and the human body. Here, we see Galileo staring down gravity, Newton breaking apart light, and Pavlov studying his now famous dogs. This is science in its most creative, hands-on form, when ingenuity of the mind is the most useful tool in the lab and the rewards of a well-considered experiment are on exquisite display.

Download or read book Zap! It's Electricity! written by Buffy Silverman and published by Britannica Digital Learning. This book was released on 2013-03-01 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intermediate readers explore electricity.

Download or read book Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research written by National Research Council and published by National Academies Press. This book was released on 2003-08-22 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expanding on the National Research Council's Guide for the Care and Use of Laboratory Animals, this book deals specifically with mammals in neuroscience and behavioral research laboratories. It offers flexible guidelines for the care of these animals, and guidance on adapting these guidelines to various situations without hindering the research process. Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research offers a more in-depth treatment of concerns specific to these disciplines than any previous guide on animal care and use. It treats on such important subjects as: The important role that the researcher and veterinarian play in developing animal protocols. Methods for assessing and ensuring an animal's well-being. General animal-care elements as they apply to neuroscience and behavioral research, and common animal welfare challenges this research can pose. The use of professional judgment and careful interpretation of regulations and guidelines to develop performance standards ensuring animal well-being and high-quality research. Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research treats the development and evaluation of animal-use protocols as a decision-making process, not just a decision. To this end, it presents the most current, in-depth information about the best practices for animal care and use, as they pertain to the intricacies of neuroscience and behavioral research.
