In the past before improving technologies allowed for the direct observation of brain activity, brain damaged patients were a prime avenue for understanding language structure and inferring back to brain function. Now with the rapid developments in neuroscience, what we do know about the brain can inform us of language allowing us to build hypotheses about the role particular brain regions perform in language use. Brain damaged patients thus become populations which serve as test cases. In this volume, the researchers focus on the interactions of frontotemporal dementia patients. These...
