Brain Mind And Internet

This essay places the emerging brain-Internet interface within a broad historical context: that the Internet represents merely the next stage in a very long history of human cognition whereby the brain couples with symbolic technologies. Understanding this 'deep history' provides a way to imagine the future of brain-Internet cognition.

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.

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.

The Internet is more than just a series of interconnected computer networks: it's the first real replication of the human brain outside the human body. To leverage its power, you first need to understand how the Internet has evolved to take on similarities to the brain. This engaging and provocative book provides the answer.

We live in a world unimaginable only decades ago: a domain of backlit screens, instant information, and vibrant experiences that can outcompete dreary reality. Our brave new technologies offer incredible opportunities for work and play. But at what price? Now renowned neuroscientist Susan Greenfield—known in the United Kingdom for challenging entrenched conventional views—brings together a range of scientific studies, news events, and cultural criticism to create an incisive snapshot of “the global now.” Disputing the assumption that our technologies are harmless tools, Greenfield explores whether incessant exposure to social media sites, search engines, and videogames is capable of rewiring our brains, and whether the minds of people born before and after the advent of the Internet differ. Stressing the impact on Digital Natives—those who’ve never known a world without the Internet—Greenfield exposes how neuronal networking may be affected by unprecedented bombardments of audiovisual stimuli, how gaming can shape a chemical landscape in the brain similar to that in gambling addicts, how surfing the Net risks placing a premium on information rather than on deep knowledge and understanding, and how excessive use of social networking sites limits the maturation of empathy and identity. But Mind Change also delves into the potential benefits of our digital lifestyle. Sifting through the cocktail of not only threat but opportunity these technologies afford, Greenfield explores how gaming enhances vision and motor control, how touch tablets aid students with developmental disabilities, and how political “clicktivism” foments positive change. In a world where adults spend ten hours a day online, and where tablets are the common means by which children learn and play, Mind Change reveals as never before the complex physiological, social, and cultural ramifications of living in the digital age. A book that will be to the Internet what An Inconvenient Truth was to global warming, Mind Change is provocative, alarming, and a call to action to ensure a future in which technology fosters—not frustrates—deep thinking, creativity, and true fulfillment. Praise for Mind Change “Greenfield’s application of the mismatch between human and machine to the brain introduces an important variation on this pervasive view of technology. . . . She has a rare talent for explaining science in accessible prose.”—The Washington Post “Greenfield’s focus is on bringing to light the implications of Internet-induced ‘mind change’—as comparably multifaceted as the issue of climate change, she argues, and just as important.”—Chicago Tribune “Mind Change is exceedingly well organized and hits the right balance between academic and provocative.”—Booklist “[A] challenging, stimulating perspective from an informed neuroscientist on a complex, fast-moving, hugely consequential field.”—Kirkus Reviews “[Greenfield] is not just an engaging communicator but a thoughtful, responsible scientist, and the arguments she makes are well-supported and persuasive.”—Mail on Sunday “Greenfield’s admirable goal to prove an empirical basis for discussion is . . . an important one.”—Financial Times “An important presentation of an uncomfortable minority position.”—Jaron Lanier, Nature

This fascinating and highly accessible book presents fantastic but totally feasible projections of what your brain may be capable of in the near future. It shows how scientific breakthroughs and amazing research are turning science fiction into science fact. In this brave new book, you'll explore: How partnerships between biological sciences and technology are helping the deaf hear, the blind see, and the paralyzed communicate. How our brains can repair and improve themselves, erase traumatic memories How we can stay mentally alert longer—and how we may be able to halt or even reverse Alzheimers How we can control technology with brain waves, including prosthetic devices, machinery, computers—and even spaceships or clones. Insights into how science may cure fatal diseases, and improve our intellectual and physical productivity Judith Horstman presents a highly informative and entertaining look at the future of your brain, based on articles from Scientific American and Scientific American Mind magazines, and the work of today’s visionary neuroscientists.
