Researchers are investigating whether a high-tech 256 dry electrode EEG cap combined with MEG readings and new fast brain modeling software can improve real-time brain source localization. The study focuses on three main questions: can this testbed better locate brain activity related to finger movement, median nerve stimulation, and speech processing? The study involves healthy adult volunteers aged 18 to 65 years. Participants will undergo detailed Magnetic Resonance Imaging (MRI) scans of the head and neck using a 7 Tesla Siemens Scanner to create precise brain models. They will then complete three different EEG tests and three MEG tests involving finger tapping with the right index finger, electrical stimulation of the median nerve at the right wrist with a response task, and listening to German sentences while performing semantic tasks. Each test collects multiple trials to record brain responses. During the study, volunteers will be monitored through MRI, EEG, and MEG scans while performing the tasks. Researchers will measure brain activity responses to the finger tapping, nerve stimulation, and speech tasks using these imaging methods over approximately one year. The goal is to compare brain source locations predicted by the testbed against known anatomical and MEG data, ensuring accurate tracking of cortical activity throughout the study.
