Functional Magnetic Resonance Imaging (fMRI) is now a standard tool for mapping activation patterns in the human brain. In this book, Richard Buxton, a leading authority on fMRI, provides an invaluable introduction to how fMRI works, from basic principles and underlying physics and physiology, to newer techniques such as arterial spin labeling and diffusion tensor imaging. The book also discusses how fMRI relates to other imaging techniques (such as Positron Emission Tomography, or PET) and offers a guide to the statistical analysis of fMRI data.
