| Abstract(in English) | We propose a variational Bayes method for estimating current source distribution from observed MEG data. In the method, we introduce a hierarchical prior which assumes that the current sources are localized in the several brain area and the current distribution is continuous. The fMRI data can be also incorporated into the hierarchical prior, so that the reliability of the estimation is increased. |
