Reorganization of language networks in aphasia takes advantage of the facts that (a) the brain is an organ of plasticity, with neuronal changes occurring throughout the life span, including following brain damage; (b) plasticity is highly experience dependent; and (c) as with any learning system, language reorganization involves a synergistic…

Fifteen years ago, Pascual-Leone and colleagues used transcranial magnetic stimulation (TMS) to investigate speech production in pre-surgical epilepsy patients and in doing so, introduced a novel tool into language research. TMS can be used to non-invasively stimulate a specific cortical region and transiently disrupt information processing. These…

Reports on linguistic features and patterns of coherence in mild and advanced levels of discourse of Alzheimer's patients. Argues and demonstrates that, as the disease progresses, patients' discourse becomes "pregrammatical"--vocabulary-driven and reliant on meaning-based discourse features rather than grammatically based features.…
