Northwestern University’s Aphasia and Neurolinguistics Research

The Aphasia and Neurolinguistics Research Laboratory investigates the effect of sentence-level treatment on language and brain recovery. Participants receive treatment focused on complex sentence structures, with recovery of untrained less complex sentences an expected outcome of treatment.

Boston University’s Aphasia Research Laboratory

The primary goal of the Boston University’s Aphasia Research Laboratory is to study the recovery of naming ability. Treatment focuses on naming objects or things within semantic categories based on their meaning and the features that connect them.

Johns Hopkins University’s Cognitive and Brain Sciences Laboratory

The CogNeuro Lab at John Hopkins University is primarily concerned with studying the effects of treatment of spelling abilities using a cognitive neuropsychologically based approach. Treatment focuses on spelling selected sets of words, with expected improvement of trained words, as well as related words with overlapping spellings.

About Us

Welcome to the Center for the Neurobiology of Language Recovery (CNLR). CNLR is supported by a $12 million National Institutes of Health (NIH), National Institute of Deafness and other Communication Disorders (NIDCD) Clinical Research Center grant. The Center is uniquely focused on research investigating how language recovers in aphasia, how treatment affects recovery, how the neural networks for language reorganize during recovery, and what factors predict language recovery.

The unprecedented Center brings together top researchers in the field to study language recovery in aphasia. The Director of CNLR, Cynthia, K. Thompson, Ph.D., is joined by Todd B. Parrish, Ph.D. at Northwestern University, as well as David Caplan, M.D., Ph.D. from Harvard University, Swathi Kiran, Ph.D., CCC-SLP from Boston University, and Brenda Rapp, Ph.D. from Johns Hopkins University.  The Center focuses its research efforts on language recovery in stroke-induced, chronic aphasia. Currently, our research investigates three different types of aphasia: agrammatism (sentence processing deficits), dysgraphia (spelling and writing deficits), and anomia (naming deficit).
