Speech pathology

We study the language processing in various brain pathologies. Primarily we are interested in the disorders in already formed language resulting from focal brain damage - aphasia. In patients with aphasia, we study psycholinguistics and neural mechanisms of speech disruption, and language and cognitive mechanisms connection: we examine the patients with the tests developed by the Lab’s members and follow neural reorganization using structural and functional neuroimaging methods. We also work with brain tumor patients: in these cases, the lesions grow slowly which enables productive neural speech reorganization. We check how this reorganization developed and follow new speech regions and pathways in order to prevent their surgical removal during the tumor resection. Our recent topics of interest - language reorganization in epilepsy and kids with impairments in speech development.
