As event-related potential (ERP) measure, the mismatch negativity (MMN) was recorded in a distracted oddball paradigm to short spoken sentences. Critical ‘deviant’ sentence stimuli where either well-formed and meaningful, or syntactically, or lexico-semantically incorrect. After 4 weeks of speech- language therapy (SLT) delivered with high intensity (10.5 h per week), clinical language assessment with the Aachen Aphasia Test battery demonstrated significant linguistic improvements, which were accompanied by enhanced MMN responses. More specifically, MMN amplitudes to grammatically correct and meaningful mini-constructions and to ‘jabberwocky’ sentences containing a pseudoword significantly increased after therapy. However, no therapy-related changes in MMN responses to syntactically incorrect strings including agreement violations were observed. While MMN increases to well-formed meaningful strings can be explained both at the word and construction levels, the neuroplastic change seen for ‘jabberwocky’ sentences suggests an explanation in terms of constructions. The results confirm previous reports that intensive SLT leads to improvements of linguistic skills in chronic aphasia patients and now demonstrate that this clinical improvement is associated with enhanced automatic brain indexes of construction processing, although no comparable change is present for ungrammatical strings. Furthermore, the data confirm that the language-induced MMN is a useful tool to map functional language recovery in PSA.","14 Seiten","https://refubium.fu-berlin.de/handle/fub188/20352||http://dx.doi.org/10.17169/refubium-23655","eng","http://creativecommons.org/licenses/by/4.0/","cortical reorganization||aphasia||syntax||EEG||intensive language therapy||mismatch negativity","600 Technik, Medizin, angewandte Wissenschaften::610 Medizin und Gesundheit::615 Pharmakologie, Therapeutik||100 Philosophie und Psychologie::150 Psychologie","Therapy-Induced Neuroplasticity of Language in Chronic Post Stroke Aphasia","A Mismatch Negativity Study of (A)Grammatical and Meaningful/less Mini- Constructions","Wissenschaftlicher Artikel","open access","Frontiers in Human Neuroscience - 10 (2017), 669","10.3389/fnhum.2016.00669","http://dx.doi.org/10.3389/fnhum.2016.00669","1662-5161","Philosophie und Geisteswissenschaften","Deutsche Forschungsgemeinschaft (DFG)","FUDOCS_derivate_000000007557","FUDOCS_document_000000026176","Gefördert durch die DFG und den Open-Access-Publikationsfonds der Freien Universität Berlin.","no"
