RecruitingDevice studyNon-Invasive Low Intensity Focused Ultrasound Stimulation for Drug-Resistant EpilepsyThe goal of this study is to investigate the effects of a non-invasive, low intensity focused ultrasound (LIFU) stimulation on seizure frequency and the epileptogenic network in drug-resistant epilepsy. LIFU uses focused sound waves to modulate deep brain regions and to enable changes in brain network activity. Encephalography (EEG) and behavioral tasks will also be used to study how LIFU affects brain activity.
