The main topic of the book is a reconstruction of the evolution of nervous systems and brains as well as of mental-cognitive abilities, in short “intelligence” from simplest organisms to humans. It investigates to which extent the two are correlated. One central topic is the alleged uniqueness of the human brain and human intelligence and mind. It is discussed which neural features make certain animals and humans intelligent and creative: Is it absolute or relative brain size or the size of “intelligence centers” inside the brains, the number of nerve cells inside the brain in total or in such “intelligence centers” decisive for the degree of intelligence, of mind and eventually consciousness? And which are the driving forces behind these processes? Finally, it is asked what all this means for the classical problem of mind-brain relationship and for a naturalistic theory of mind.
“A History of the Human Brain is a unique, enlightening, and provocative account of the most significant question we can ask about ourselves.” —Richard Wrangham, author of The Goodness Paradox Just 125,000 years ago, humanity was on a path to extinction, until a dramatic shift occurred. We used our mental abilities to navigate new terrain and changing climates. We hunted, foraged, tracked tides, shucked oysters—anything we could do to survive. Before long, our species had pulled itself back from the brink and was on more stable ground. What saved us? The human brain—and its evolutionary journey is unlike any other. In A History of the Human Brain, Bret Stetka takes us on this far-reaching journey, explaining exactly how our most mysterious organ developed. From the brain’s improbable, watery beginnings to the marvel that sits in the head of Home sapiens today, Stetka covers an astonishing progression, even tackling future brainy frontiers such as epigenetics and CRISPR. Clearly and expertly told, this intriguing account is the story of who we are. By examining the history of the brain, we can begin to piece together what it truly means to be human.
In The Evolution of Mind, outstanding figures on the cutting edge of evolutionary psychology follow clues provided by current neuroscientific evidence to illuminate many puzzling questions of human cognitive evolution. With contributions from psychologists, ethologists, anthropologists, and philosophers, the book offers a broad range of approaches to explore the mysteries of the mind's evolution - from investigating the biological functions of human cognition to drawing comparisons between human and animal cognitive abilities.
The extraordinary story of how the human brain evolved… and is still evolving. We’ve come a long way. The earliest human had a brain as small as a child’s fist; ours are four times bigger, with spectacular abilities and potential we are only just beginning to understand. This is How the Mind Changed, a seven-million-year journey through our own heads, packed with vivid stories, groundbreaking science, and thrilling surprises. Discover how memory has almost nothing to do with the past; meditation rewires our synapses; magic mushroom use might be responsible for our intelligence; climate accounts for linguistic diversity; and how autism teaches us hugely positive lessons about our past and future. Dr. Joseph Jebelli’s In Pursuit of Memory was shortlisted for the Royal Society Science Book Prize and longlisted for the Wellcome. In this, his eagerly awaited second book, he draws on deep insights from neuroscience, evolutionary biology, psychology, and philosophy to guide us through the unexpected changes that shaped our brains. From genetic accidents and environmental forces to historical and cultural advances, he explores how our brain’s evolution turned us into Homo sapiens and beyond. A single mutation is all it takes.
Attractively illustrated with over a hundred halftones and drawings, this volume presents a series of vibrant profiles that trace the evolution of our knowledge about the brain. Beginning almost 5000 years ago, with the ancient Egyptian study of "the marrow of the skull," Stanley Finger takes us on a fascinating journey from the classical world of Hippocrates, to the time of Descartes and the era of Broca and Ramon y Cajal, to modern researchers such as Sperry. Here is a truly remarkable cast of characters. We meet Galen, a man of titanic ego and abrasive disposition, whose teachings dominated medicine for a thousand years; Vesalius, a contemporary of Copernicus, who pushed our understanding of human anatomy to new heights; Otto Loewi, pioneer in neurotransmitters, who gave the Nazis his Nobel prize money and fled Austria for England; and Rita Levi-Montalcini, discoverer of nerve growth factor, who in war-torn Italy was forced to do her research in her bedroom. For each individual, Finger examines the philosophy, the tools, the books, and the ideas that brought new insights. Finger also looks at broader topics--how dependent are researchers on the work of others? What makes the time ripe for discovery? And what role does chance or serendipity play? And he includes many fascinating background figures as well, from Leonardo da Vinci and Emanuel Swedenborg to Karl August Weinhold--who claimed to have reanimated a dead cat by filling its skull with silver and zinc--and Mary Shelley, whose Frankenstein was inspired by such experiments. Wide ranging in scope, imbued with an infectious spirit of adventure, here are vivid portraits of giants in the field of neuroscience--remarkable individuals who found new ways to think about the machinery of the mind.
Sir John Eccles, a distinguished scientist and Nobel Prize winner who has devoted his scientific life to the study of the mammalian brain, tells the story of how we came to be, not only as animals at the end of the hominid evolutionary line, but also as human persons possessed of reflective consciousness.
Aimed at advanced undergraduate and graduate students, this textbook describes some of the basic principles affecting brain evolution. The author refers to data from a wide array of vertebrates while minimizing technical jargon. Particular attention has been paid to the ways in which changes in brain structure impact function and behavior. The volume concludes with a discussion on how mammal brains diverged from other brains and how Homo sapiens evolved a very large and special brain.
How did the human brain with all its manifold capacities evolve from basic functions in simple organisms that lived nearly a billion years ago? John Allman addresses this question in Evolving Brains, a provocative study of brain evolution that introduces readers to some of the most exciting developments in science in recent years.
Two neuroscientists reveal why consciousness exists and how it works by examining eighteen increasingly intelligent minds, from microbes to humankind—and beyond. Why do you exist? How did atoms and molecules transform into sentient creatures that experience longing, regret, compassion, and even marvel at their own existence? What does it truly mean to have a mind—to think? Science has offered few answers to these existential questions until now. Journey of the Mind is the first book to offer a unified account of the mind that explains how consciousness, language, self-awareness, and civilization arose incrementally out of chaos. The journey begins three billion years ago with the emergence of the universe’s simplest possible mind. From there, the book explores the nanoscopic archaeon, whose thinking machinery consists of a handful of molecules, then advances through amoebas, worms, frogs, birds, monkeys, and humans, explaining what each “new” mind could do that previous minds could not. Though they admire the triumph of human consciousness, Ogi Ogas and Sai Gaddam argue that humans are hardly the most sophisticated minds on the planet. The same physical principles that produce human self-awareness are leading cities and nation-states to develop “superminds,” and perhaps planting the seeds for even higher forms of consciousness. Written in lively, accessible language accompanied by vivid illustrations, Journey of the Mind is a mind-bending work of popular science, the first general book to share the cutting-edge mathematical basis for consciousness, language, and the self. It shows how a “unified theory of the mind” can explain the mind’s greatest mysteries—and offer clues about the ultimate fate of all minds in the universe.
The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."
