Abstract

Recent investigations have explored how large-scale systems in the brain operate in the processes of retrieving knowledge for words and concepts. Much of the crucial evidence derives from lesion studies, because word retrieval and concept retrieval can be clearly dissociated in brain-damaged individuals. We discuss these findings from the perspective of our neurobiological framework, which is cited in Pulvermüller's target article.
