Memoirs of an Addicted Brain: A Neuroscientist Examines his Former Life on Drugs
Marc Lewis - 2011
This cycle is at the root of all addictions, addictions to drugs, sex, love, cigarettes, soap operas, wealth, and wisdom itself. But why should this be so? Why are we desperate for what we don't have, or can't have, often at great cost to what we do have, thereby risking our peace and contentment, our safety, and even our lives?"The answer, says Dr. Marc Lewis, lies in the structure and function of the human brain. Marc Lewis is a distinguished neuroscientist. And, for many years, he was a drug addict himself, dependent on a series of dangerous substances, from LSD to heroin. His narrative moves back and forth between the often dark, compellingly recounted story of his relationship with drugs and a revelatory analysis of what was going on in his brain. He shows how drugs speak to the brain - which is designed to seek rewards and soothe pain - in its own language. He shows in detail the neural mechanics of a variety of powerful drugs and of the onset of addiction, itself a distortion of normal perception.Dr. Lewis freed himself from addiction and ended up studying it. At the age of 30 he traded in his pharmaceutical supplies for the life of a graduate student, eventually becoming a professor of developmental psychology, and then of neuroscience - his field for the last 12 years. This is the story of his journey, seen from the inside out.

The Re-Origin of Species: A Second Chance for Extinct Animals
Torill Kornfeldt - 2016
Their tools in this hunt are both fossils and cutting-edge genetic technologies. Some of these scientists are driven by sheer curiosity; others view the lost species as a powerful weapon in the fight to preserve rapidly changing ecosystems. It seems certain that these animals will walk the earth again, but what world will that give us? And is any of this a good idea? Science journalist Torill Kornfeldt travelled the world to meet the men and women working to bring these animals back from the dead. Along the way, she has seen the mammoth that has been frozen for 20,000 years, and visited the places where these furry giants will live again.
Networks of the Brain
Olaf Sporns - 2010
Increasingly, science is concerned with the structure, behavior, and evolution of complex systems ranging from cells to ecosystems. In Networks of the Brain, Olaf Sporns describes how the integrative nature of brain function can be illuminated from a complex network perspective.Highlighting the many emerging points of contact between neuroscience and network science, the book serves to introduce network theory to neuroscientists and neuroscience to those working on theoretical network models. Sporns emphasizes how networks connect levels of organization in the brain and how they link structure to function, offering an informal and nonmathematical treatment of the subject. Networks of the Brain provides a synthesis of the sciences of complex networks and the brain that will be an essential foundation for future research.
Forensics: What Bugs, Burns, Prints, DNA and More Tell Us About Crime
Val McDermid - 2014
To the right listener, they tell us all about themselves: where they came from, how they lived, how they died - and who killed them. Forensic scientists can unlock the mysteries of the past and help justice to be done using the messages left by a corpse, a crime scene or the faintest of human traces. Forensics uncovers the secrets of forensic medicine, drawing on interviews with top-level professionals, ground-breaking research and Val McDermid's own experience to lay bare the secrets of this fascinating science. And, along the way, she wonders at how maggots collected from a corpse can help determine time of death, how a DNA trace a millionth the size of a grain of salt can be used to convict a killer and how a team of young Argentine scientists led by a maverick American anthropologist uncovered the victims of a genocide.In her crime novels, Val McDermid has been solving complex crimes and confronting unimaginable evil for years. Now, she's looking at the people who do it for real, and real crime scenes. It's a journey that will take her to war zones, fire scenes and autopsy suites, and bring her into contact with extraordinary bravery and wickedness, as she traces the history of forensics from its earliest beginnings to the cutting-edge science of the modern day.
Sapiens: A Brief History of Humankind
Yuval Noah Harari - 2011
Today there is just one. Us. Homo sapiens. How did our species succeed in the battle for dominance? Why did our foraging ancestors come together to create cities and kingdoms? How did we come to believe in gods, nations and human rights; to trust money, books and laws; and to be enslaved by bureaucracy, timetables and consumerism? And what will our world be like in the millennia to come? In Sapiens, Dr Yuval Noah Harari spans the whole of human history, from the very first humans to walk the earth to the radical – and sometimes devastating – breakthroughs of the Cognitive, Agricultural and Scientific Revolutions. Drawing on insights from biology, anthropology, paleontology and economics, he explores how the currents of history have shaped our human societies, the animals and plants around us, and even our personalities. Have we become happier as history has unfolded? Can we ever free our behaviour from the heritage of our ancestors? And what, if anything, can we do to influence the course of the centuries to come? Bold, wide-ranging and provocative, Sapiens challenges everything we thought we knew about being human: our thoughts, our actions, our power ... and our future.
Brainscapes: The Warped, Wondrous Maps Written in Your Brain—And How They Guide You
Rebecca Schwarzlose - 2021
Your brain is a collection of maps. That is no metaphor: scrawled across your brain’s surfaces are actual maps of the sights, sounds, and actions that hold the key to your survival. Scientists first began uncovering these maps over a century ago, but we are only now beginning to unlock their secrets—and comprehend their profound impact on our lives. Brain maps distort and shape our experience of the world, support complex thought, and make technology-enabled mind reading a modern-day reality, which raises important questions about what is real, what is fair, and what is private. They shine a light on our past and our possible futures. In the process, they invite us to view ourselves from a startling new perspective. In Brainscapes, Rebecca Schwarzlose combines unforgettable real-life stories, cutting-edge research, and vivid illustrations to reveal brain maps’ surprising lessons about our place in the world—and about the world’s place within us.
What Kind of Creatures Are We?
Noam Chomsky - 2015
In these lectures, he presents a lifetime of philosophical reflection on all three of these areas of research, to which he has contributed for over half a century.In clear, precise, and nontechnical language, Chomsky elaborates on fifty years of scientific development in the study of language, sketching how his own work has implications for the origins of language, the close relations that language bears to thought, and its eventual biological basis. He expounds and criticizes many alternative theories, such as those that emphasize the social, the communicative, and the referential aspects of language. Chomsky reviews how new discoveries about language overcome what seemed to be highly problematic assumptions in the past. He also investigates the apparent scope and limits of human cognitive capacities and what the human mind can seriously investigate, in the light of history of science and philosophical reflection and current understanding. Moving from language and mind to society and politics, he concludes with a searching exploration and philosophical defense of a position he describes as "libertarian socialism," tracing its links to anarchism and the ideas of John Dewey and even to the ideas of Marx and Mill, demonstrating its conceptual growth out of our historical past and urgent relation to matters of the present.
Hooked: Food, Free Will, and How the Food Giants Exploit Our Addictions
Michael Moss - 2021
Our bodies are hardwired for sweets, so food giants have developed fifty-six types of sugar to add to their products, creating in us the expectation that everything should be cloying; we've evolved to prefer fast, convenient meals, hence our modern-day preference for ready-to-eat foods. Moss goes on to show how the processed food industry--including major companies like Nestlé, Mars, and Kellogg's--has tried not only to evade this troubling discovery about the addictiveness of food but to actually exploit it. For instance, in response to recent dieting trends, food manufacturers have simply turned junk food into junk diets, filling grocery stores with "diet" foods that are hardly distinguishable from the products that got us into trouble in the first place. As obesity rates continue to climb, manufacturers are now claiming to add ingredients that can effortlessly cure our compulsive eating habits. An account of the legal battles, insidious marketing campaigns, and cutting-edge food science that have brought us to our current public health crisis, Moss lays out all that the food industry is doing to exploit and deepen our addictions, and shows us why what we eat has never mattered more.From the #1 New York Times bestselling author of Salt Sugar Fat comes a powerful exposé of how the processed food industry exploits our evolutionary instincts, the emotions we associate with food, and legal loopholes in their pursuit of profit over public health.
The Optimism Bias: A Tour of the Irrationally Positive Brain
Tali Sharot - 2011
Psychologists have long been aware that most people maintain an often irrationally positive outlook on life. In fact, optimism may be crucial to our existence. Tali Sharot’s experiments, research, and findings in cognitive science have contributed to an increased understanding of the biological basis of optimism. In this fascinating exploration, she takes an in-depth, clarifying look at how the brain generates hope and what happens when it fails; how the brains of optimists and pessimists differ; why we are terrible at predicting what will make us happy; how emotions strengthen our ability to recollect; how anticipation and dread affect us; and how our optimistic illusions affect our financial, professional, and emotional decisions. With its cutting-edge science and its wide-ranging and accessible narrative, The Optimism Bias provides us with startling new insight into the workings of the brain.From the Hardcover edition.

Arrival of the Fittest: Solving Evolution's Greatest Puzzle
Andreas Wagner - 2014
Nature’s many innovations—some uncannily perfect—call for natural principles that accelerate life’s ability to innovate.”Darwin’s theory of natural selection explains how useful adaptations are preserved over time. But the biggest mystery about evolution eluded him. As genetics pioneer Hugo de Vries put it, “natural selection may explain the survival of the fittest, but it cannot explain the arrival of the fittest.”Can random mutations over a mere 3.8 billion years really be responsible for wings, eyeballs, knees, camouflage, lactose digestion, photosynthesis, and the rest of nature’s creative marvels? And if the answer is no, what is the mechanism that explains evolution’s speed and efficiency?In Arrival of the Fittest, renowned evolutionary biologist Andreas Wagner draws on over fifteen years of research to present the missing piece in Darwin's theory. Using experimental and computational technologies that were heretofore unimagined, he has found that adaptations are not just driven by chance, but by a set of laws that allow nature to discover new molecules and mechanisms in a fraction of the time that random variation would take.Consider the Arctic cod, a fish that lives and thrives within six degrees of the North Pole, in waters that regularly fall below 0 degrees. At that temperature, the internal fluids of most organisms turn into ice crystals. And yet, the arctic cod survives by producing proteins that lower the freezing temperature of its body fluids, much like antifreeze does for a car’s engine coolant. The invention of those proteins is an archetypal example of nature’s enormous powers of creativity. Meticulously researched, carefully argued, evocatively written, and full of fascinating examples from the animal kingdom, Arrival of the Fittest offers up the final puzzle piece in the mystery of life’s rich diversity.
Physics in Mind: A Quantum View of the Brain
Werner R. Loewenstein - 2013
But what is the mind? What do we mean when we say we are "aware" of something? What is this peculiar state in our heads, at once utterly familiar and bewilderingly mysterious, that we call awareness or consciousness? In Physics in Mind, eminent biophysicist Werner R. Loewenstein argues that to answer these questions, we must first understand the physical mechanisms that underlie the workings of the mind. And so begins an exhilarating journey along the sensory data stream of the brain, which shows how our most complex organ processes the vast amounts of information coming in through our senses to create a coherent, meaningful picture of the world. Bringing information theory to bear on recent advances in the neurosciences, Loewenstein reveals a web of immense computational power inside the brain. He introduces the revolutionary idea that quantum mechanics could be fundamental to how our minds almost instantaneously deal with staggering amounts of information, as in the case of the information streaming through our eyes. Combining cutting-edge research in neuroscience and physics, Loewenstein presents an ambitious hypothesis about the parallel processing of sensory information that is the heart, hub, and pivot of the cognitive brain. Wide-ranging and brimming with insight, Physics in Mind breaks new ground in our understanding of how the mind works.
