Projections

“Because of his experiences as a physician and researcher, Dr. Deisseroth recognizes the limitations of science and medicine and the transcendent value of elemental human connection. . . . In life’s most difficult moments, it might be everything.”—The Wall Street Journal

“Deisseroth achieves the difficult feat of moving and enlightening the reader at the same time.”—The Guardian

“[Karl Deisseroth’s] imaginative narrative flows effortlessly. . . . There is a first love of reading and writing and hints of a literary imagination that draws on James Joyce and Toni Morrison. . . . His narratives are always sensitive. . . . An admixture of fact and fiction, reality and imagination, damage and desire.”—Science

“Poetic, mind-stretching, and through it all, deeply human.”—Daniel Levitin, New York Times bestselling author of The Organized Mind

“Karl Deisseroth intertwines neuroscience and human stories in a way that is altogether new: technical, lyrical, and deeply compassionate all at once.This is a crucial book for anyone who loves science, anyone who loves someone who is suffering from a disorder of the brain, or anyone who, like so many of us, loves both.”—Lucy Kalanithi

“Projections asks probing questions about some of our most fundamental human traits to shed light on the origins of our emotions. Why, for instance, do we shed tears? How did this show of weakness survive millennia of evolution? Deisseroth writes of heartbreaking and desperate medical cases with a doctor’s knowledge and a novelist’s skill for narrative. I was fascinated, and could not put this book down.”—May-Britt Moser, Nobel Laureate

“We are living during a revolution in our understanding of the human brain, and Karl Deisseroth has been at the forefront of these advances. This magisterial work, Projections,  shows that not only is he one of our leading scientists, but also a gifted writer and storyteller. With precise yet luminous prose, he merges stories of cutting-edge neuroscience with a deep reverence for his patients’ humanity.”—Neil Shubin, author of Some Assembly Required

“Unique and utterly riveting . . . This is a masterpiece written for each and every one of us.”—Patricia Churchland, author of Conscience

“I’ve known Karl as a colleague, a scientist whose discoveries in the lab have been breathtaking and revolutionary. Maybe I shouldn’t be surprised to discover he’s also a stunning writer . . . Projections is a tour de force.”—Abraham Verghese, author of Cutting for Stone

“An engaging, accessible blend of psychology and science, which sets itself apart with Deisseroth’s lyrical writing and the empathy of his storytelling.”—Library Journal (starred review)

Texte du rabat

In this groundbreaking tour of the human mind, a renowned psychiatrist and neuroscientist explores the biological and evolutionary origins of human emotions through poignant, and at times shocking, clinical stories.

Karl Deisseroth has spent his life pursuing truths about the human mind, both as a practicing clinical psychiatrist and as a researcher who created the revolutionary field of optogenetics, which allows us to decipher the brain's inner workings using light. In Projections, he combines his groundbreaking access to the brain's inner circuitry with a deep empathy for his patients to examine what mental illness reveals about the mind and the origin of human feelings--how the broken can illuminate the unbroken.
An internationally acclaimed professor of bioengineering and psychiatry at Stanford, Deisseroth's true passion is clinical psychiatry, and it is the stories of his patients that form the backbone of Projections. Through these case studies, he tells the larger story of how we can understand the physical and biological origins of human emotion in the brain. As such, he describes vividly how humans experience feelings both in the simple and ancient circuits of our brains and in the poignant moments of suffering in our daily lives. The stories of Deisseroth's patients are rich with humanity and shine an unprecedented light on the self and the ways in which it breaks down. A young woman with an eating disorder reveals how the mind can rebel against the brain's most primitive drives of hunger and thirst; while an older gentleman, smothered into silence by depression and dementia, illuminates how humans evolved to feel joy and its absence; and a lonely Uyghur woman far from home teaches the importance of rich social bonds.
An illuminating and essential work, Projections transforms the way we understand the brain as a biological and as an emotional object.

Résumé
A groundbreaking tour of the human mind that illuminates the biological nature of our inner worlds and emotions, through gripping, moving—and, at times, harrowing—clinical stories

“[A] scintillating and moving analysis of the human brain and emotions.”—Nature

“Beautifully connects the inner feelings within all human beings to deep insights from modern psychiatry and neuroscience.”—Robert Lefkowitz, Nobel Laureate

Karl Deisseroth has spent his life pursuing truths about the human mind, both as a renowned clinical psychiatrist and as a researcher creating and developing the revolutionary field of optogenetics, which uses light to help decipher the brain’s workings. In Projections, he combines his knowledge of the brain’s inner circuitry with a deep empathy for his patients to examine what mental illness reveals about the human mind and the origin of human feelings—how the broken can illuminate the unbroken.

Through cutting-edge research and gripping case studies from Deisseroth’s own patients, Projections tells a larger story about the material origins of human emotion, bridging the gap between the ancient circuits of our brain and the poignant moments of suffering in our daily lives. The stories of Deisseroth’s patients are rich with humanity and shine an unprecedented light on the self—and the ways in which it can break down. A young woman with an eating disorder reveals how the mind can rebel against the brain’s most primitive drives of hunger and thirst; an older man, smothered into silence by depression and dementia, shows how humans evolved to feel not only joy but also its absence; and a lonely Uighur woman far from her homeland teaches both the importance—and challenges—of deep social bonds.

Illuminating, literary, and essential, Projections is a revelatory, immensely powerful work. It transforms our understanding not only of the brain but of ourselves as social beings—giving vivid illustrations through science and resonant human stories of our yearning for connection and meaning.

The Faraday Cage

Hegel made famous his aphorism that all the rational is real and all the real rational; but there are many of us who, unconvinced by Hegel, continue to believe that the real, the really real, is irrational, that reason builds upon irrationalities. Hegel, a great framer of definitions, attempted with definitions to reconstruct the universe, like that artiller…
