Book Description
At once far flung and intimate, a fascinating look at how finding our way make us human. In this compelling narrative, O'Connor seeks out neuroscientists, anthropologists and master navigators to understand how navigation ultimately gave us our humanity. Biologists have been trying to solve the mystery of how organisms have the ability to migrate and orient with such precision—especially since our own adventurous ancestors spread across the world without maps or instruments. O'Connor goes to the Arctic, the Australian bush and the South Pacific to talk to masters of their environment who seek to preserve their traditions at a time when anyone can use a GPS to navigate. O’Connor explores the neurological basis of spatial orientation within the hippocampus. Without it, people inhabit a dream state, becoming amnesiacs incapable of finding their way, recalling the past, or imagining the future. Studies have shown that the more we exercise our cognitive mapping skills, the greater the grey matter and health of our hippocampus. O'Connor talks to scientists studying how atrophy in the hippocampus is associated with afflictions such as impaired memory, dementia, Alzheimer’s Disease, depression and PTSD. Wayfinding is a captivating book that charts how our species' profound capacity for exploration, memory and storytelling results in topophilia, the love of place. "O'Connor talked to just the right people in just the right places, and her narrative is a marvel of storytelling on its own merits, erudite but lightly worn. There are many reasons why people should make efforts to improve their geographical literacy, and O'Connor hits on many in this excellent book—devouring it makes for a good start." —Kirkus Reviews

Book Description
How the brain helps us to understand and navigate space—and why, sometimes, it doesn’t work the way it should. Inside our heads we carry around an infinite and endlessly unfolding map of the world. Navigation is one of the most ancient neural abilities we have—older than language. In Dark and Magical Places, Christopher Kemp embarks on a journey to discover the remarkable extent of what our minds can do. Fueled by his own spatial shortcomings, Kemp describes the brain regions that orient us in space and the specialized neurons that do it. Place cells. Grid cells. He examines how the brain plans routes, recognizes landmarks, and makes sure we leave a room through a door instead of trying to leave through a painting. From the secrets of supernavigators like the indigenous hunters of the Bolivian rainforest to the confusing environments inhabited by people with place blindness, Kemp charts the myriad ways in which we find our way and explains the cutting-edge neuroscience behind them. How did Neanderthals navigate? Why do even seasoned hikers stray from the trail? What spatial skills do we inherit from our parents? How can smartphones and our reliance on GPS devices impact our brains? In engaging, engrossing language, Kemp unravels the mysteries of navigating and links the brain’s complex functions to the effects that diseases like Alzheimer’s, types of amnesia, and traumatic brain injuries have on our perception of the world around us. A book for anyone who has ever felt compelled to venture off the beaten path, Dark and Magical Places is a stirring reminder of the beauty in losing yourself to your surroundings. And the beauty in understanding how our brains can guide us home.

Book Description
A wise and insightful exploration of human navigation, what it means to be lost, and how we find our way. How is it that we can walk unfamiliar streets while maintaining a sense of direction? Come up with shortcuts on the fly, in places we’ve never traveled? The answer is the complex mental map in our brains. This feature of our cognition is easily taken for granted, but it’s also critical to our species’ evolutionary success. In From Here to There Michael Bond tells stories of the lost and found—Polynesian sailors, orienteering champions, early aviators—and surveys the science of human navigation. Navigation skills are deeply embedded in our biology. The ability to find our way over large distances in prehistoric times gave Homo sapiens an advantage, allowing us to explore the farthest regions of the planet. Wayfinding also shaped vital cognitive functions outside the realm of navigation, including abstract thinking, imagination, and memory. Bond brings a reporter’s curiosity and nose for narrative to the latest research from psychologists, neuroscientists, animal behaviorists, and anthropologists. He also turns to the people who design and expertly maneuver the world we navigate: search-and-rescue volunteers, cartographers, ordnance mappers, urban planners, and more. The result is a global expedition that furthers our understanding of human orienting in the natural and built environments. A beguiling mix of storytelling and science, From Here to There covers the full spectrum of human navigation and spatial understanding. In an age of GPS and Google Maps, Bond urges us to exercise our evolved navigation skills and reap the surprising cognitive rewards.

Book Description
This book examines the ethical and legal challenges presented by modern techniques of memory retrieval, especially within the context of potential use by the US government in courts of law. Specifically, Marc Blitz discusses the Fourth Amendment’s protections against unreasonable searches and the Fifth Amendment's self-incrimination clause. He also argues that we should pay close attention to another constitutional provision that individuals generally don’t think of as protecting their privacy: The First Amendment’s freedom of speech. First Amendment values also protect our freedom of thought, and this—not simply our privacy—is what is at stake if government engaged in excessive monitoring of our minds.

Book Description
Navigation is the key human skill. It's something we do everywhere, whether feeling our way through a bedroom in the dark, or charting a ship's course. But how does navigation affect our brains, our memory, ourselves? Blending scientific research and memoir, and written in beautiful prose, Finding North starts with a quest by the author to understand this most basic of human skills---and why it's in mortal peril. In 1844, Foy's great-great grandfather, captain of a Norwegian cargo ship, perished at sea after getting lost in a snowstorm. Foy decides to unravel the mystery surrounding Halvor Michelsen's death---and the roots of his own obsession with navigation---by re-creating his ancestor's trip using only period instruments. Beforehand, he meets a colorful cast of characters to learn whether men really have better directional skills than women, how cells, eels, and spaceships navigate; and how tragedy results from GPS glitches. He interviews a cabby who has memorized every street in London, sails on a Haitian cargo sloop, and visits the site of a secret navigational cult in Greece. At the heart of Foy's story is this fact: navigation and the brain's memory centers are inextricably linked. As Foy unravels the secret behind Halvor's death, he also discovers why forsaking our navigation skills in favor of GPS may lead not only to Alzheimers and other diseases of memory, but to losing a key part of what makes us human.

Book Description
A Wired Most Fascinating Book of the Year “An important book that reminds us that navigation remains one of our most underappreciated arts.” —Tristan Gooley, author of The Lost Art of Reading Nature’s Signs “If you want to understand what rats can teach us about better-planned cities, why walking into a different room can help you find your car keys, or how your brain’s grid, border, and speed cells combine to give us a sense of direction, this book has all the answers.” —The Scotsman How is it that some of us can walk unfamiliar streets without losing our way, while the rest of us struggle even with a GPS? Navigating in uncharted territory is a remarkable feat if you stop to think about it. In this beguiling mix of science and storytelling, Michael Bond explores how we do it: how our brains make the “cognitive maps” that keep us orientated and how that anchors our sense of wellbeing. Children are instinctive explorers, developing a spatial understanding as they roam. And yet today few of us make use of the wayfinding skills that we inherited from our nomadic ancestors. Bond tells stories of the lost and found—sailors, orienteering champions, early aviators—and explores why being lost can be such a devastating experience. He considers how our understanding of the world around us affects our psychology and helps us see how our reliance on technology may be changing who we are. “Bond concludes that, by setting aside our GPS devices, by redesigning parts of our cities and play areas, and sometimes just by letting ourselves get lost, we can indeed revivify our ability to find our way, to the benefit of our inner world no less than the outer one.” —Science “A thoughtful argument about how our ability to find our way is integral to our nature.” —Sunday Times
