摘要：
This paper proposes a method for estimation source of brain electrical activity from magnetoencephalography surface recordings using Frost filter and Tikhonov regularization. The Frost filter is implemented to monitor activity from a location of interest and block signals from elsewhere, the Tikhonov regularization is used to improve the conditioning of the covariance matrix inversion of the measured data. The efficacy of the approach is verified through the application to realistic MEG simulations.
