About This Trial
The goal of this research study is to optimize the parameter of Low-Intensity Focused Ultrasound Stimulation (LIFUS) that is most effective in changing cortical excitability and motor learning skills in patients who suffered a stroke. The researchers hope to answer two questions.
* with increasing power, would LIFUS be more effective?
* with the same power, what LIFUS timing is the best
