Projekt 6

Effects of DBS on Speech and Language Functions

With this project we strive to analyze the effect of Deep Brain Stimulation (DBS) on language and speech functions. This is pursued against the background of frequently reported adverse effects of DBS on language and speech as well as in regard of the controversially discussed conceptualization of subcortical language processing. In order to comprehensively describe biolinguistic functions, we examine patients with different neurological movement disorders treated with DBS of distinct target areas. By applying neurophysiological, psychometrical and behavioral methods two complementary approaches are followed. The first encompasses the examination of patients accomplishing a variety of language and speech tasks under active versus inactive DBS. Secondly, deep brain recordings are performed directly from the target areas of DBS immediately after the implantation. Thus the role of basal ganglia and thalamic regions in language related processes can be investigated by measuring changes of neural activation during task performance.

Aiming at a further optimization of DBS therapy the project is accomplished in close cooperation with project 3, 8 and 9 of the clinical research group.
