Description
Functional Magnetic Resonance Imaging (fMRI) is now a standard tool for mapping activation patterns in the human brain. This highly interdisciplinary field involves neuroscientists and physicists as well as clinicians, and the range, flexibility and sophistication of the techniques being used are increasing rapidly. In this book, Richard Buxton, a leading authority on fMRI, provides an invaluable introduction to how fMRI works, from basic principles and the underlying physics and physiology, to newer techniques such as arterial spin labeling and diffusion tensor imaging. The book also includes discussion of how fMRI relates to other imaging techniques (such as Positron Emission Tomography, or PET) and a guide to the statistical analysis of fMRI data. This book will be useful both to the experienced researcher using fMRI, and the clinician or researcher with no previous knowledge of the technology.
