The origin‎,‎ development‎,‎ and nature of language has been the focus of theoretical debate among philosophers for many centuries‎.‎ Following the pioneering clinical observations 150 years ago of loss of language following a cerebral lesion‎,‎ language started to be considered a biological system‎,‎ that could be investigated scientifically‎.‎ As a consequence‎,‎ an increasing number of scientists began to search for its anatomical and functional basis and its links with other such cognitive systems‎.‎ The relatively recent introduction of neuroimaging tools‎,‎ such as PET and fMRI‎,‎ has brought rapid and groundbreaking developments to the field of Neurolinguistics‎.‎ In this book‎,‎ Denes harnesses these advances to adopt a biolinguistic approach to the study of a subject that increasingly sees the collaboration of linguists‎,‎ experimental psychologists‎,‎ neuroscientists and clinicians‎.‎ Talking Heads reviews the latest research to provide a concise analysis of the multifaceted aspects of language which focuses both on theoretical aspects and physical implementation‎.‎ Following an up‎-to‎-date description of acquired language disorders‎,‎ and their contribution to the design of a functional architecture of language‎,‎ the book illustrates the neurological process involved in the production and comprehension of spoken and written language‎,‎ as well as investigating the neurological and functional systems responsible for sign language production and first and second language acquisition‎.‎ With a glossary of the anatomical and linguistic terms‎,‎ this book provides an invaluable resource to undergraduate and graduate students of psychology‎,‎ psycholinguistics and linguistics‎.‎
