Mutual inhibition of verbal areas of the brain after stroke and its effect in speech therapy

Contralateral inhibition of the motoric language area in left sided ischemia and its effect on language performance

Time: Wednesday, November 26 at 17:30

Organizer: Netherlands ANT Neuro company

In all right-handed patients and in the majority of left-handed patients, the dominant speech area (Broca’s) is located in the left hemisphere. The non-dominant speech area of the right hemisphere (i.e. the homologous area) is variable in size and has variable activity. These two centers are connected through the corpus callosum. Activity in the left Broca’s area inhibits the homologous right area.

However, if the main Broca’s area is damaged for any reason (tumor, trauma, encephalitis), the right center becomes partially dominant while inhibiting the remaining activity of the left hemisphere via the corpus callosum. This is harmful during the speech therapy of these patients, because in this condition, language training does not affect the damaged left side and only affects the healthy right homologous area. To overcome this problem during speech therapy, the right homologous area should be weakened to force the brain to use the left Broca’s area. This can be done with TMS and tDCS methods before the speech therapy session.

In this webinar, more details about the protocols and findings in this area will be presented. This webinar will be presented by Prof. Alexander Hartmann, neurologist and professor of neurology at the University of Witten/Herdek. He has a lot of experience in preoperative and intraoperative mapping of patients with neurological diseases.
