| Abstract(in English) | Current source estimation problem of Magnetoencephalography is defined as an ill-posed inverse problem because the signal source dimension is generally presumed to be higher than the observation dimension. In order to solve this problem, many kinds of constraints have been proposed. However, almost all proposed methods are suitable for task-related brain activity and there is no method which optimized for resting-state yet. Considering the actual resting-state dynamics, each source is connected through structural connectivity composed of nerve bundles and communicated with time delay according to length of connectivity. Therefore, we propose a source estimation method which achieve the robust estimation for resting-state using structural connectivity. We demonstrate the performance of estimation using simulation data. |
