You might be aware of these references, but if not, they could be helpful:

%A P.L. Nunez
%A K.L. Pilgreen
%T The spline-Laplacian in clinical neurophysiology:
   A method to improve EEG spatial resolution
%J J. Clin. Neurophysiol.
%V 8

%T Neocortical Dynamics and Human EEG Rhythms

The recent 1995 book has chapters on the Laplacian methods as well as
a chapter by Gevins and Cutillo.
