| Abstract(in English) | We haveproposed a variational Bayes method for estimating current source distribution from 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. In this report, we have done commit er simulation by using the cortex model obtained by MRI measurement. The simulation results shows the effectiveness of our method. |
