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 Spark written by Timothy J. Jorgensen and published by Princeton University Press. This book was released on 2023-06-06 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fresh look at electricity and its powerful role in life on Earth When we think of electricity, we likely imagine the energy humming inside our home appliances or lighting up our electronic devices—or perhaps we envision the lightning-streaked clouds of a stormy sky. But electricity is more than an external source of power, heat, or illumination. Life at its essence is nothing if not electrical. The story of how we came to understand electricity’s essential role in all life is rooted in our observations of its influences on the body—influences governed by the body’s central nervous system. Spark explains the science of electricity from this fresh, biological perspective. Through vivid tales of scientists and individuals—from Benjamin Franklin to Elon Musk—Timothy Jorgensen shows how our views of electricity and the nervous system evolved in tandem, and how progress in one area enabled advancements in the other. He explains how these developments have allowed us to understand—and replicate—the ways electricity enables the body’s essential functions of sight, hearing, touch, and movement itself. Throughout, Jorgensen examines our fascination with electricity and how it can help or harm us. He explores a broad range of topics and events, including the Nobel Prize–winning discoveries of the electron and neuron, the history of experimentation involving electricity’s effects on the body, and recent breakthroughs in the use of electricity to treat disease. Filled with gripping adventures in scientific exploration, Spark offers an indispensable look at electricity, how it works, and how it animates our lives from within and without.

Download or read book Discovering the Brain written by National Academy of Sciences and published by National Academies Press. This book was released on 1992-01-01 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."

Book excerpt: Science journalist Sally Adee breaks open the field of bioelectricity—the electric currents that run through our bodies and every living thing—its misunderstood history, and why new discoveries will lead to new ways around antibiotic resistance, cleared arteries, and new ways to combat cancer. You may be familiar with the idea of our body's biome: the bacterial fauna that populate our gut and can so profoundly affect our health. In We Are Electric we cross into new scientific understanding: discovering your body's electrome. Every cell in our bodies—bones, skin, nerves, muscle—has a voltage, like a tiny battery. It is the reason our brain can send signals to the rest of our body, how we develop in the womb, and why our body knows to heal itself from injury. When bioelectricity goes awry, illness, deformity, and cancer can result. But if we can control or correct this bioelectricity, the implications for our health are remarkable: an undo switch for cancer that could flip malignant cells back into healthy ones; the ability to regenerate cells, organs, even limbs; to slow aging and so much more. The next scientific frontier might be decrypting the bioelectric code, much the way we did the genetic code. Yet the field is still emerging from two centuries of skepticism and entanglement with medical quackery, all stemming from an 18th-century scientific war about the nature of electricity between Luigi Galvani (father of bioelectricity, famous for shocking frogs) and Alessandro Volta (inventor of the battery). In We Are Electric, award-winning science writer Sally Adee takes readers through the thrilling history of bioelectricity and into the future: from the Victorian medical charlatans claiming to use electricity to cure everything from paralysis to diarrhea, to the advances helped along by the giant axons of squids, and finally to the brain implants and electric drugs that await us—and the moral implications therein. The bioelectric revolution starts here.
Download or read book The Ambiguous Frog written by Marcello Pera and published by Princeton University Press. This book was released on 2014-07-14 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do ideas become accepted by the scientific community? How and why do scientists choose among empirically equivalent theories? In this pathbreaking book translated from the Italian, Marcello Pera addresses these questions by exploring the politics, rhetoric, scientific practices, and metaphysical assumptions that entered into the famous Galvani-Volta controversy of the late eighteenth century. This lively debate erupted when two scientists, each examining the muscle contractions of a dissected frog in contact with metal, came up with opposing but experimentally valid explanations of the phenomenon. Luigi Galvani, a doctor and physiologist, believed that he had discovered animal electricity (electrical body fluid existing naturally in a state of disequilibrium), while the physicist Alessandro Volta attributed the contractions to ordinary physical electricity. Beginning with the electrical concepts understood by scientists in the 1790s, Pera traces the careers of Galvani and Volta and explains their laboratory procedures. He shows that their controversy derived from two basic, irreducible interpretations of the proper nature of a common domain: Galvani saw the frog phenomenon as the work of biological organs, Volta as that of a physical apparatus. The initial preference for Volta's theory, maintains Pera, depended not on clear-cut methodological rules, but on a dialectical dispute for which the renowned physicist was better equipped, partly because he shared the dominant metaphysical views of his time.
