| Abstract(in English) | The power increase/decrease of EEG rhythms (event-related synchronization/desynchronization, ERS/ERD) is often used to investigate human brain activities. When subjects execute movements and their imageries, ERS and ERD are observed in the vicinity of the sensorymotor area and the brain activity mostly in the primary motor area is also observed by fMRI. In this study, signal power related to ERS and ERD of μ rhythm (8-13Hz) were estimated by applying prewhitening beamformer with linear constraints to measured EEG and fMRI data during right/left wrist bending movements. It was found that the centers of estimated signal power of ERS and ERD of μ rhythm were located in the ipsilateral and contralateral sensorimotor area, respectively. This demonstrates that prewhitening beamformer with linear constraints is available for signal source estimation of ERS and/or ERD. |
