Welcome to ANT Neuro Educational Webinar Series!
In all right-handed and in the majority of left-handed patients the dominant speech center (Broca center) is located in the left hemisphere. The right hemispheric non-dominant speech center (i.e. the homologue center) is of variable size and possesses variable activity. Both centers are connected by fibers via the corpus callosum. The activity of the left sided Broca center inhibits the homologue right sided center. However, if the original Broca center suffers from any damage (infarct, tumor, trauma, encephalitis), the right center partially takes over and – at the same time – inhibits the remaining activity of the left hemispheric center via the corpus callosum. This is of disadvantage during speech therapy of these patients, since under these circumstances language training does not support the suffering left side but only the healthy right homologue center. To overcome this problem during speech therapy, one has to impair the right homologue center to force the brain to use the left sided diseased Broca center (forced use). This goal can be achieved by TMS and tDCS methods shortly before speech therapy. In this webinar, we will present more details on protocols and findings.
Our presenter Prof. Alexander Hartmann, MD, is a neurologist at the Clinics of the City of Cologne and Professor of Neurology at the Witten/Herdecke University. He has extensive experience in preoperative and intraoperative mapping of patients with neurological disorders.
We look forward to welcoming you to this webinar!
