Brain surface current density reconstructions are widely used to analyze magnetoencephalographic data arising from electrical activity in the human brain. Commonly, this mapping is performed in single subjects. We present a methodology to apply brain surface current density mapping to group studies. The technique includes stepwise transformation of the magnetic sensors into a standard sensor system and linear scaling of individual heads in Talairach space. We demonstrate the usefulness of the technique with a comparison of the motor activation in pianist and non-pianist while listening to piano pieces.
