Book Description
Whether we realize it or not, we think of our brains as computers. In neuroscience, the metaphor of the brain as a computer has defined the field for much of the modern era. But as neuroscientists increasingly reevaluate their assumptions about how brains work, we need a new metaphor to help us ask better questions. The computational neuroscientist Daniel Graham offers an innovative paradigm for understanding the brain. He argues that the brain is not like a single computer—it is a communication system, like the internet. Both are networks whose power comes from their flexibility and reliability. The brain and the internet both must route signals throughout their systems, requiring protocols to direct messages from just about any point to any other. But we do not yet understand how the brain manages the dynamic flow of information across its entire network. The internet metaphor can help neuroscience unravel the brain’s routing mechanisms by focusing attention on shared design principles and communication strategies that emerge from parallel challenges. Highlighting similarities between brain connectivity and the architecture of the internet can open new avenues of research and help unlock the brain’s deepest secrets. An Internet in Your Head presents a clear-eyed and engaging tour of brain science as it stands today and where the new paradigm might take it next. It offers anyone with an interest in brains a transformative new way to conceptualize what goes on inside our heads.

Book Description
Finalist for the 2011 Pulitzer Prize in General Nonfiction: “Nicholas Carr has written a Silent Spring for the literary mind.”—Michael Agger, Slate “Is Google making us stupid?” When Nicholas Carr posed that question, in a celebrated Atlantic Monthly cover story, he tapped into a well of anxiety about how the Internet is changing us. He also crystallized one of the most important debates of our time: As we enjoy the Net’s bounties, are we sacrificing our ability to read and think deeply? Now, Carr expands his argument into the most compelling exploration of the Internet’s intellectual and cultural consequences yet published. As he describes how human thought has been shaped through the centuries by “tools of the mind”—from the alphabet to maps, to the printing press, the clock, and the computer—Carr interweaves a fascinating account of recent discoveries in neuroscience by such pioneers as Michael Merzenich and Eric Kandel. Our brains, the historical and scientific evidence reveals, change in response to our experiences. The technologies we use to find, store, and share information can literally reroute our neural pathways. Building on the insights of thinkers from Plato to McLuhan, Carr makes a convincing case that every information technology carries an intellectual ethic—a set of assumptions about the nature of knowledge and intelligence. He explains how the printed book served to focus our attention, promoting deep and creative thought. In stark contrast, the Internet encourages the rapid, distracted sampling of small bits of information from many sources. Its ethic is that of the industrialist, an ethic of speed and efficiency, of optimized production and consumption—and now the Net is remaking us in its own image. We are becoming ever more adept at scanning and skimming, but what we are losing is our capacity for concentration, contemplation, and reflection. Part intellectual history, part popular science, and part cultural criticism, The Shallows sparkles with memorable vignettes—Friedrich Nietzsche wrestling with a typewriter, Sigmund Freud dissecting the brains of sea creatures, Nathaniel Hawthorne contemplating the thunderous approach of a steam locomotive—even as it plumbs profound questions about the state of our modern psyche. This is a book that will forever alter the way we think about media and our minds.

Book Description
"Beautifully written, eloquently reasoned…Mr. Buonomano takes us off and running on an edifying scientific journey." —Carol Tavris, Wall Street Journal In Your Brain Is a Time Machine, leading neuroscientist Dean Buonomano embarks on an "immensely engaging" exploration of how time works inside the brain (Barbara Kiser, Nature). The human brain, he argues, is a complex system that not only tells time, but creates it; it constructs our sense of chronological movement and enables "mental time travel"—simulations of future and past events. These functions are essential not only to our daily lives but to the evolution of the human race: without the ability to anticipate the future, mankind would never have crafted tools or invented agriculture. This virtuosic work of popular science will lead you to a revelation as strange as it is true: your brain is, at its core, a time machine.

Book Description
A warning, a movement, a collection borne of protest. In Watch Your Head, poems, stories, essays, and artwork sound the alarm on the present and future consequences of the climate emergency. Ice caps are melting, wildfires are raging, and species extinction is accelerating. Dire predictions about the climate emergency from scientists, Indigenous land and water defenders, and striking school children have mostly been ignored by the very institutions – government, education, industry, and media – with the power to do something about it. Writers and artists confront colonization, racism, and the social inequalities that are endemic to the climate crisis. Here the imagination amplifies and humanizes the science. These works are impassioned, desperate, hopeful, healing, transformative, and radical. This is a call to climate-justice action. Edited by Madhur Anand, Stephen Collis, Jennifer Dorner, Catherine Graham, Elena Johnson, Canisia Lubrin, Kim Mannix, Kathryn Mockler, June Pak, Sina Queyras, Shazia Hafiz Ramji, Rasiqra Revulva, Yusuf Saadi, Sanchari Sur, and Jacqueline Valencia Proceeds will be donated to RAVEN and Climate Justice Toronto.

Book Description
BRILLIANTLY EXPLORING TODAY'S CUTTING-EDGE BRAIN RESEARCH, MIND WIDE OPEN IS AN UNPRECEDENTED JOURNEY INTO THE ESSENCE OF HUMAN PERSONALITY, ALLOWING READERS TO UNDERSTAND THEMSELVES AND THE PEOPLE IN THEIR LIVES AS NEVER BEFORE. Using a mix of experiential reportage, personal storytelling, and fresh scientific discovery, Steven Johnson describes how the brain works -- its chemicals, structures, and subroutines -- and how these systems connect to the day-to-day realities of individual lives. For a hundred years, he says, many of us have assumed that the most powerful route to self-knowledge took the form of lying on a couch, talking about our childhoods. The possibility entertained in this book is that you can follow another path, in which learning about the brain's mechanics can widen one's self-awareness as powerfully as any therapy or meditation or drug. In Mind Wide Open, Johnson embarks on this path as his own test subject, participating in a battery of attention tests, learning to control video games by altering his brain waves, scanning his own brain with a $2 million fMRI machine, all in search of a modern answer to the oldest of questions: who am I? Along the way, Johnson explores how we "read" other people, how the brain processes frightening events (and how we might rid ourselves of the scars those memories leave), what the neurochemistry is behind love and sex, what it means that our brains are teeming with powerful chemicals closely related to recreational drugs, why music moves us to tears, and where our breakthrough ideas come from. Johnson's clear, engaging explanation of the physical functions of the brain reveals not only the broad strokes of our aptitudes and fears, our skills and weaknesses and desires, but also the momentary brain phenomena that a whole human life comprises. Why, when hearing a tale of woe, do we sometimes smile inappropriately, even if we don't want to? Why are some of us so bad at remembering phone numbers but brilliant at recognizing faces? Why does depression make us feel stupid? To read Mind Wide Open is to rethink family histories, individual fates, and the very nature of the self, and to see that brain science is now personally transformative -- a valuable tool for better relationships and better living.

Book Description
"Provocative enough to make you start questioning your each and every action."—Entertainment Weekly The brain's power is confirmed and touted every day in new studies and research. And yet we tend to take our brains for granted, without suspecting that those masses of hard-working neurons might not always be working for us. Cordelia Fine introduces us to a brain we might not want to meet, a brain with a mind of its own. She illustrates the brain's tendency toward self-delusion as she explores how the mind defends and glorifies the ego by twisting and warping our perceptions. Our brains employ a slew of inborn mind-bugs and prejudices, from hindsight bias to unrealistic optimism, from moral excuse-making to wishful thinking—all designed to prevent us from seeing the truth about the world and the people around us, and about ourselves.

Book Description
A neurologist explores the very real world of psychosomatic illness. Most of us accept the way our heart flutters when we set eyes on the one we secretly admire, or the sweat on our brow as we start the presentation we do not want to give. But few of us are fully aware of how dramatic our body's reactions to emotions can sometimes be. Take Pauline, who first became ill when she was fifteen. What seemed at first to be a urinary infection became joint pain, then food intolerances, then life-threatening appendicitis. And then one day, after a routine operation, Pauline lost all the strength in her legs. Shortly after that her convulsions started. But Pauline's tests are normal; her symptoms seem to have no physical cause whatsoever. Pauline may be an extreme case, but she is by no means alone. As many as a third of men and women visiting their GP have symptoms that are medically unexplained. In most, an emotional root is suspected and yet, when it comes to a diagnosis, this is the very last thing we want to hear, and the last thing doctors want to say. In It's All in Your Head consultant neurologist Dr Suzanne O'Sullivan takes us on a journey through the very real world of psychosomatic illness. She takes us from the extreme -- from paralysis, seizures and blindness -- to more everyday problems such as tiredness and pain. Meeting her patients, she encourages us to look deep inside the human condition. There we find the secrets we are all capable of keeping from ourselves, and our age-old failure to credit the intimate and extraordinary connection between mind and body.

Book Description
The World In Your Head: A Gestalt View of the Mechanism of Conscious Experience represents a bold assault on one of the greatest unsolved mysteries in science: the nature of consciousness and the human mind. Rather than examining the brain and nervous system to see what they tell us about the mind, this book begins with an examination of conscious experience to see what it can tell us about the brain. Through this analysis, the first and most obvious observation is that consciousness appears as a volumetric spatial void, containing colored objects and surfaces. This reveals that the representation in the brain takes the form of an explicit volumetric spatial model of external reality. Therefore, the world we see around us is not the real world itself, but merely a miniature virtual-reality replica of that world in an internal representation. In fact, the phenomena of dreams and hallucinations clearly demonstrate the capacity of the brain to construct complete virtual worlds even in the absence of sensory input. Perception is somewhat like a guided hallucination, based on sensory stimulation. This insight allows us to examine the world of visual experience not as scientists exploring the external world, but as perceptual scientists examining a rich and complex internal representation. This unique approach to investigating mental function has implications in a wide variety of related fields, including the nature of language and abstract thought, and motor control and behavior. It also has implications to the world of music, art, and dance, showing how the patterns of regularity and periodicity in space and time--apparent in those aesthetic domains--reflect the periodic basis set of the underlying harmonic resonance representation in the brain.
