Stroke is the leading cause for acquired disability in adults. Non-invasive brain stimulation of the primary motor cortex can enhance motor recovery. However, there is relevant intersubject variability in the response. Posteroparietal brain regions might serve as alternative targets. This project aims at investigating this approach in a group of chronic stroke patients. We will address stimulation-related changes in cortical excitability of the motor network and changes in motor functioning. We hypothesize that the results will help to promote this region as an innovative alternative target region for brain stimulation.
