Karl Deisseroth

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 LaureateKarl 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.

In this riveting journey through the hidden realms of the human mind, a world-renowned psychiatrist and neuroscientist explores the origins of human emotion, and examines what mental illnesses reveal about all of us - how the broken can illuminate the unbroken.Why do we feel what we feel?Mental illness is one of the greatest causes of human suffering, but the reasons we bear this burden, and the nature of these diseases, have remained mysterious. Now, our understanding has reached a tipping point. In Connections , Professor Karl Deisseroth intertwines gripping case studies from his experience as an emergency psychiatry physician, with breakthrough scientific discoveries from astounding new technology (including optogenetics, which he developed to allow turning specific brain cells on or off, with light).By linking insights from this technology to deeply moving stories of his patients and to our shared evolutionary history, Deisseroth tells a larger story about the origins of human emotion. 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 dementia, shows how humans evolved to feel joy and its absence; and a lonely Uyghur woman far from her homeland teaches both the importance - and challenges - of deep social bonds.Addressing some of the most timeless questions about the human condition while illuminating the roots of misunderstood disorders such as depression, psychosis, schizophrenia and sociopathy, Connections transforms the way we understand the brain, and our selves.
