Today, says Dale Purves, the dominant research agenda may have taken us as far as it can--and neuroscientists may be approaching a paradigm shift. In this highly personal book, Purves reveals how we got to this point and offers his notion of where neuroscience may be headed next. Purves guides you through a half-century of the most influential ideas in neuroscience and introduces the extraordinary scientists and physicians who created and tested them. Purves offers a critical assessment of the paths that neuroscience research has taken, their successes and their limitations, and then introduces an alternative approach for thinking about brains. Building on new research on visual perception, he shows why common ideas about brain networks can't be right and uncovers the factors that determine our subjective experience. The resulting insights offer a deeper understanding of what it means to be human. - Why we need a better conception of what brains are trying to do and how they do it Approaches to understanding the brain over the past several decades may be at an impasse - The surprising lessons that can be learned from what we see How complex neural processes owe more to trial-and-error experience than to logical principles - Brains--and the people who think about them Meet some of the extraordinary individuals who've shaped neuroscience - The -ghost in the machine- problem The ideas presented further undermine the concept of free will

    The Keys are designed for easy visual comparison of details which look alike, narrowing the identification of a tree to one of a small group -- the family or genus.Then, in the Master Pages, the species of the tree is determined, with similar details placed together to highlight differences within the family group, thus eliminating all other possibilities. The details of the Oak trees on this plate are an example of the system.All of the more than 1500 photographs were made specifically for use in this book and were taken either in the field or of carefully collected specimens. Where possible, details such as leaves, fruit, etc., appear in actual size, or in the same scale.

    Two tiny pits located inside the nostril, long thought to be vestigial, Jacobson's Organ may in fact be an intrinsic part of our mammalian senses. In this entertaining and informative book, Watson rescues our most underappreciated sense from obscurity. He brings to light new evidence that this evolutionary apparatus, discovered in 1811, is the pheromonal mechanism that triggers the areas of the brain affecting awareness, emotion, and sexual behavior. This highly refined sense can help us determine everything from the suitability of potential mates to identifying offspring, and offers insight into how, why, and what we remember. Filled with surprising and delightful anecdotes, Jacobson's Organ sniffs out the scientific truths behind a wide range of phenomena and behaviors in the plant, animal, and human worlds.

    As written by priests, explorers, adventurers, natural historians, and anthropologists, the pieces express the wonder of strangers in new worlds. Who were these extraordinary magic-makers who imitated the sounds of animals in the night, or drank tobacco juice through funnels, or wore collars filled with stinging ants?Shamans Through Time is a rare chronicle of changing attitudes toward that which is strange and unfamiliar. With essays by such acclaimed thinkers as Claude Lévi-Strauss, Black Elk, Carlos Castaneda, and Frank Boas, it provides an awesome glimpse into the incredible shamanic practices of cultures around the world.

    Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    In this newly revised edition, chapters have been rewritten to accommodate the impact of computer technology and the Internet, not only on the acquisition and analysis of data, but also on its organization and presentation. Alternatives to the use of radiation have been expanded, and figures and illustrations have been redrawn to reflect changes in laboratory equipment and procedures.

    Conventional wisdom may be wrong. In this controversial book, the eminent biologist Paul W. Ewald offers some startling arguments:-Germs appear to be at the root of heart disease, Alzheimer’s, schizophrenia, many forms of cancer, and other chronic diseases.-The greatest threats to our health come not from sensational killers such as Ebola, West Nile virus, and super-virulent strains of influenza, but from agents that are already here causing long-term infections, which eventually lead to debilitation and death. -The medical establishment has largely ignored the evidence that implicates these germs, to the detriment of our public health.-New evolutionary theories are available, which explain how germs function and offer opportunities for controlling these modern plagues — if we are willing to listen to them.Plague Time is an eye-opening exploration of the revolutionary new understanding of disease that may set the course of medical research for the twenty-first century.

    Combining methods from history, astronomy, physics, and biology to draw together the big story arcs of how the universe was created, why planets formed, and how life developed, the result is a unique perspective of mankind’s place in the universe.Excited by the alternative "framework for all knowledge" that is offered by this approach, Bill Gates is funding the Big History Project, which aims to bring this concept to a wider audience around the world.The Little Book of Big History breaks down the main themes of Big History into highly informative and accessible parts for all readers to enjoy. By giving a truly complete timeline of world events, this book shines a whole different light on science as we learned it and makes us think of our history—and our future—in a very different way.

    The pictorial models are useful in understanding relationships. The models also abound in descriptive detail.

    Remember the fad a few years ago when people wore bracelets reminding them, “What Would Jesus Do?” Christians state that Jesus is the example of how to live, yet this has been limited in many cases to how we view our moral character. When Christians tell me that they want to live like Jesus, I like to ask if they have multiplied food, healed the sick, walked on water, raised the dead, paid their taxes with fish money, calmed storms, and so forth. I typically receive bewildered looks, but that’s what it is like to live like Jesus!Perhaps we are ignoring a large portion of what living like Jesus really includes. While I agree that we are to live like Jesus, “Those who say they live in God should live their lives as Jesus did” (1 John 2:6 NLT). I am also aware that the application of Jesus’ model has been minimized to something that can be accomplished by living a moral life. Many Christians believe that they can live like Jesus without ever operating in the supernatural. After reading in the Bible about all of the miracles He performed, does that sound right to you?

    Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences.Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren't found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of Sao Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices like Pranayama, Sudarshan Kriya, and Tummo and teams up with pulmonary tinkerers to scientifically test long-held beliefs about how we breathe.Modern research is showing us that making even slight adjustments to the way we inhale and exhale can jump-start athletic performance; rejuvenate internal organs; halt snoring, asthma, and autoimmune disease; and even straighten scoliotic spines. None of this should be possible, and yet it is.Drawing on thousands of years of medical texts and recent cutting-edge studies in pulmonology, psychology, biochemistry, and human physiology, Breath turns the conventional wisdom of what we thought we knew about our most basic biological function on its head. You will never breathe the same again.

    . . a book that enriches our understanding of how the struggle to think new thoughts is shared across time and space and people.”—The Sunday Telegraph (London)Christmas, 1859. Just one month after the publication of On the Origin of Species, Charles Darwin received an unsettling letter. He had expected criticism; in fact, letters were arriving daily, most expressing outrage and accusations of heresy. But this letter was different. It accused him of failing to acknowledge his predecessors, of taking credit for a theory that had already been discovered by others. Darwin realized that he had made an error in omitting from Origin of Species any mention of his intellectual forebears. Yet when he tried to trace all of the natural philosophers who had laid the groundwork for his theory, he found that history had already forgotten many of them.Darwin’s Ghosts tells the story of the collective discovery of evolution, from Aristotle, walking the shores of Lesbos with his pupils, to Al-Jahiz, an Arab writer in the first century, from Leonardo da Vinci, searching for fossils in the mine shafts of the Tuscan hills, to Denis Diderot in Paris, exploring the origins of species while under the surveillance of the secret police, and the brilliant naturalists of the Jardin de Plantes, finding evidence for evolutionary change in the natural history collections stolen during the Napoleonic wars. Evolution was not discovered single-handedly, Rebecca Stott argues, contrary to what has become standard lore, but is an idea that emerged over many centuries, advanced by daring individuals across the globe who had the imagination to speculate on nature’s extraordinary ways, and who had the courage to articulate such speculations at a time when to do so was often considered heresy.With each chapter focusing on an early evolutionary thinker, Darwin’s Ghosts is a fascinating account of a diverse group of individuals who, despite the very real dangers of challenging a system in which everything was presumed to have been created perfectly by God, felt compelled to understand where we came from. Ultimately, Stott demonstrates, ideas—including evolution itself—evolve just as animals and plants do, by intermingling, toppling weaker notions, and developing over stretches of time. Darwin’s Ghosts presents a groundbreaking new theory of an idea that has changed our very understanding of who we are.
