Looking Inside the Brain (ebook)

Argumento de Looking Inside the Brain (ebook)

Denis Le Bihan is internationally recognized for his contributions to the development of imaging methods for the study of the human brain. He is the founding director of NeuroSpin, an institute of the French Atomic Energy Commission dedicated to ultra-high-field brain imaging. He won the 2012 Honda Prize, Japan’s international award for science and technology, and the 2014 Louis-Jeantet Prize for Medicine.

"[L]ooking Inside the Brain introduces readers to basic neuroanatomy and sets out to explain how neuroimaging has helped scientists better understand human emotion, cognitive faculties, and neurological illnesses, including cancer and psychiatric disorders. Interestingly, Le Bihan describes the functions of these technologies through a probing account of the water molecule, whose fascinating properties make these technologies work. Besides the historical accounts of these technologies, the real value of this work is the author’s forward-looking predictions regarding the future of these technologies and their continued evolution."--Choice

"Written by the inventor of diffusion MRI, Looking Inside the Brain is a well-informed and accessible book that explores the major outcomes and breakthroughs of brain imaging."--Jean-Pierre Changeux, coauthor of The Good, the True, and the Beautiful and What Makes Us Think?

"Modern neuroscience provides daring insight into the incredibly complex organ that is the brain--insight based on vast volumes of data obtained by the most sophisticated technology. Le Bihan is uniquely qualified to tell the story of brain imaging, from both neurological and technical perspectives."--R. Nick Bryan, emeritus professor of radiology, University of Pennsylvania

"Who better to lead us into the technological wonderland of in vivo brain imaging than Denis Le Bihan, pioneer of diffusion magnetic resonance imaging (dMRI)? [A] densely factual narrative."--Barbara Kiser, Nature

"Le Bihan, an innovative scientist whose research has led to bold advancements in the field of neuroimaging, explains the historical evolution of imaging technology. . . . Le Bihan's book, which is packed with photographs and witty asides, is an accessible explanation of a complex, technological topic."--Library Journal0Acknowledgments vii
