This book deals with neuroimaging of the brain, head, neck, and spine. During the last few years, there have been considerable advances in this subject, driven by clinical as well as technological developments. The authors, internationally renowned experts in their field, have contributed chapters that are disease-oriented and cover all relevant imaging modalities, including magnetic resonance imaging, computed tomography, and positron emission tomography. As a result, this book offers a comprehensive review of the state of the art in neuroimaging.

The Contrastive Hierarchy in Phonology

'Contrast' - the opposition between distinctive sounds in a language - is one of the most central concepts in linguistics. This book presents an original account of the logic and history of contrast in phonology. It provides empirical evidence from diverse phonological domains that only contrastive features are computed by the phonological component of grammar. It argues that the contrastive specifications of phonemes are governed by language-particular feature hierarchies.
