An Internet in Your Head

Graham offers a fresh, insightful, and informative perspective on brain function, proposing that communication between neurons resembles signal passing in the internet as a novel metaphor to investigate the brain. He provides erudite discussions and presents compelling arguments in a lively and clear manner. -- Gabriel Kreiman, Harvard Medical School Ever since we began to explore the brain, we have used various metaphors, typically relating brains to machines. Von Neumann introduced the computer metaphor but the list of similarities faded away with time. Daniel Graham's book updates the brain-is-like metaphor to encompass the internet. Unlike the computer, the internet is not a blueprint design but a constantly evolving system, much like the brain. Or perhaps it is not the entire brain but only the neocortex is like the internet, which contains all knowledge of the individual, the way the internet contains all factual knowledge of humankind. Yet, only through efficient searching can knowledge become accessible; luckily, there is the hippocampus, the brain's search engine. Of course, metaphors can be reciprocated. Does the internet have plans, feelings, and intentions?

A must-read for anyone interested in the brain from the novice to the hardened professional, Graham's book bravely challenges the standard dogma to reshape and reframe our thinking about the workings of the brain. -- Michael S. Gazzaniga, director of the SAGE Center for the Study of Mind, University of California Santa Barbara, and author of <i>The Consciousness Instinct: Unraveling the Mystery of How the Brain Makes the Mind</i> Brain function cannot be fully understood without considering how neurons and brain regions connect and communicate. What are the principles that govern how rich and dynamic patterns of network communication organize and support mind and cognition? This book offers a truly enjoyable and accessible account of this important topic, as well as a fresh and thought-provoking perspective that bridges brain science and modern communication technology. -- Olaf Sporns, distinguished professor of psychological and brain sciences, Indiana University The brain and the internet both require flexibility for reliably routing information across growing and adapting networks. Graham's accessible and scholarly book, which also considers mail and telephone networks, develops plausible similarities for how brains and internets solve routing problems. -- Chris McManus, professor of psychology, University College London, and author of <i>Right Hand, Left Hand: The Origins of Asymmetry in Brains, Bodies, Atoms, and Cultures</i>
