Livewired

You will never think about your brain in the same way again. The brain is often portrayed as an organ with different regions dedicated to specific tasks. But that textbook model is wrong. The brain is a dynamic system, constantly modifying its own circuitry to match the demands of the environment and the body in which it finds itself. If you were to zoom into the living, microscopic cosmos inside the skull, you would witness tentacle-like extensions grasping, bumping, sensing, searching for the right connections to establish or forego, like denizens of a country establishing friendships, marriages, neighbourhoods, political parties, vendettas, and social networks. It's a mysterious kind of computational material, an organic three-dimensional textile that adjusts itself to operate with maximum efficiency. The brain is not hardwired, David Eagleman contends--it is livewired. With his new theory of infotropism, Eagleman demonstrates why the fundamental principle of the brain is information maximization: in the same way that plants grow toward light, brains reconfigure to boost data from the outside world. Follow Eagleman on a thrilling journey to discover how a child can function with one half of his brain removed, how a blind man can hit a baseball via a sensor on his tongue, how new devices and body plans can enhance our natural capacities, how paralyzed people will soon be able to dance in thought-controlled robotic suits, how we can build the next generation of devices based on the principles of the brain, and what all this has to do with why we dream at night.

This enlightening examination of creativity looks “at art and science together to examine how innovations . . . build on what already exists and rely on three brain operations: bending, breaking and blending” (The Wall Street Journal) The Runaway Species is a deep dive into the creative mind, a celebration of the human spirit, and a vision of how we can improve our future by understanding and embracing our ability to innovate. David Eagleman and Anthony Brandt seek to answer the question: what lies at the heart of humanity’s ability—and drive—to create? Our ability to remake our world is unique among all living things. But where does our creativity come from, how does it work, and how can we harness it to improve our lives, schools, businesses, and institutions? Eagleman and Brandt examine hundreds of examples of human creativity through dramatic storytelling and stunning images in this beautiful, full–color volume. By drawing out what creative acts have in common and viewing them through the lens of cutting–edge neuroscience, they uncover the essential elements of this critical human ability, and encourage a more creative future for all of us. “The Runaway Species approach[es] creativity scientifically but sensitively, feeling its roots without pulling them out.” —The Economist

At once funny, wistful and unsettling, Sum is a dazzling exploration of unexpected afterlives—each presented as a vignette that offers a stunning lens through which to see ourselves in the here and now. In one afterlife, you may find that God is the size of a microbe and unaware of your existence. In another version, you work as a background character in other people’s dreams. Or you may find that God is a married couple, or that the universe is running backward, or that you are forced to live out your afterlife with annoying versions of who you could have been. With a probing imagination and deep understanding of the human condition, acclaimed neuroscientist David Eagleman offers wonderfully imagined tales that shine a brilliant light on the here and now.

Locked in the silence and darkness of your skull, your brain fashions the rich narratives of your reality and your identity. Join renowned neuroscientist David Eagleman for a journey into the questions at the mysterious heart of our existence. What is reality? Who are “you”? How do you make decisions? Why does your brain need other people? How is technology poised to change what it means to be human? In the course of his investigations, Eagleman guides us through the world of extreme sports, criminal justice, facial expressions, genocide, brain surgery, gut feelings, robotics, and the search for immortality. Strap in for a whistle-stop tour into the inner cosmos. In the infinitely dense tangle of billions of brain cells and their trillions of connections, something emerges that you might not have expected to see in there: you. This is the story of how your life shapes your brain, and how your brain shapes your life. (A companion to the six-part PBS series. Color illustrations throughout.)

Storytelling, a tradition that built human civilization, may soon destroy it Humans are storytelling animals. Stories are what make our societies possible. Countless books celebrate their virtues. But Jonathan Gottschall, an expert on the science of stories, argues that there is a dark side to storytelling we can no longer ignore. Storytelling, the very tradition that built human civilization, may be the thing that destroys it. In The Story Paradox, Gottschall explores how a broad consortium of psychologists, communications specialists, neuroscientists, and literary quants are using the scientific method to study how stories affect our brains. The results challenge the idea that storytelling is an obvious force for good in human life. Yes, storytelling can bind groups together, but it is also the main force dragging people apart. And it’s the best method we’ve ever devised for manipulating each other by circumventing rational thought. Behind all civilization’s greatest ills—environmental destruction, runaway demagogues, warfare—you will always find the same master factor: a mind-disordering story. Gottschall argues that societies succeed or fail depending on how they manage these tensions. And it has only become harder, as new technologies that amplify the effects of disinformation campaigns, conspiracy theories, and fake news make separating fact from fiction nearly impossible. With clarity and conviction, Gottschall reveals why our biggest asset has become our greatest threat, and what, if anything, can be done. It is a call to stop asking, “How we can change the world through stories?” and start asking, “How can we save the world from stories?”

Revealing the neuroscience and genetics behind synesthesia—and how this multi-sensory phenomenon changed our view of the brain. A person with synesthesia might feel the flavor of food on her fingertips, sense the letter “J” as shimmering magenta or the number “5” as emerald green, hear and taste her husband’s voice as buttery golden brown. Synesthetes rarely talk about their peculiar sensory gift—believing either that everyone else senses the world exactly as they do, or that no one else does. Yet synesthesia occurs in 1 in 20 people, and is even more common among artists. One famous synesthete was novelist Vladimir Nabokov, who insisted as a toddler that the colors on his wooden alphabet blocks were “all wrong.” His mother understood exactly what he meant because she, too, had synesthesia. Nabokov's son Dmitri, who recounts this tale in the afterword to this book, is also a synesthete—further illustrating how synesthesia runs in families. Wednesday Is Indigo Blue reveals how the extraordinary multisensory phenomenon of synesthesia has changed our traditional view of the brain. Because synesthesia contradicted existing theory, researcher Richard Cytowic spent 20 years persuading colleagues that it was a real—and important—brain phenomenon rather than a mere curiosity. Today, scientists in 15 countries are exploring synesthesia and how it is changing the traditional view of how the brain works. Cytowic and neuroscientist David Eagleman argue that perception is already multisensory, though for most of us its multiple dimensions exist beyond the reach of consciousness. Reality, they point out, is more subjective than most people realize. No mere curiosity, synesthesia is a window on the mind and brain, highlighting the amazing differences in the way people see the world.

If the conscious mind—the part you consider to be you—is just the tip of the iceberg, what is the rest doing? In this sparkling and provocative new book, the renowned neuroscientist David Eagleman navigates the depths of the subconscious brain to illuminate surprising mysteries: Why can your foot move halfway to the brake pedal before you become consciously aware of danger ahead? Why do you hear your name being mentioned in a conversation that you didn’t think you were listening to? What do Ulysses and the credit crunch have in common? Why did Thomas Edison electrocute an elephant in 1916? Why are people whose names begin with J more likely to marry other people whose names begin with J? Why is it so difficult to keep a secret? And how is it possible to get angry at yourself—who, exactly, is mad at whom? Taking in brain damage, plane spotting, dating, drugs, beauty, infidelity, synesthesia, criminal law, artificial intelligence, and visual illusions, Incognito is a thrilling subsurface exploration of the mind and all its contradictions.

“A fascinating look at how scientists are working to help doctors treat the aging process itself, helping us all to lead longer, healthier lives.” —Sanjay Gupta, MD Aging—not cancer, not heart disease—is the underlying cause of most human death and suffering. The same cascade of biological changes that renders us wrinkled and gray also opens the door to dementia and disease. We work furiously to conquer each individual disease, but we never think to ask: Is aging itself necessary? Nature tells us it is not: there are tortoises and salamanders who are spry into old age and whose risk of dying is the same no matter how old they are, a phenomenon known as “biological immortality.” In Ageless, Andrew Steelecharts the astounding progress science has made in recent years to secure the same for humans: to help us become old without getting frail, to live longer without ill health or disease.
