This textbook provides a true introduction to functional magnetic resonance imaging (fMRI), which has become the dominant research technique in cognitive neuroscience. Although there is extraordinary interest in fMRI among researchers and instructors alike, two problems have hampered the study of this technique. First, existing texts are targeted toward practicing scientists in the field and assume a level of expertise not possessed by most students. Second, most students do not have access to fMRI equipment and data, so they have no opportunity to gain hands on experience. This textbook overcomes these limitations by presenting a comprehensive overview of all aspects of fMRI, designed with undergraduate students, graduate students and beginning researchers in mind. The authors' goal was to create a book that is sufficiently scientifically rigorous for scientists in the field, but also accessible enough to be easily read and understood by beginning students. The book can be used as the primary text for classes in fMRI, or as a secondary text for cognitive neuroscience, research methods or other courses.
