Laplacians in EEG/EP/ERP analysis

Is anyone familiar with the surface Laplacian techniques of EEG and
evoked potential/event-related potential analysis, as described in Law, SK
et al. "Improving spatial and temporal resolution in evoked EEG
responses using surface Laplacians." Electroenceph. & clin Neurophys
88(1993)309-322?  I'm wondering if the technique can be applied to some
of the work we're doing, but I lack sufficient mathematical expertise to
really evaluate it.  I'm in the process of collecting the references in that
article's bibliography, but opinions from people with hands-on experience
with the method would be invaluable.

Also, if anyone has the first author's (Samuel K. Law, Ph.D.) email
address, I'd appreciate it.

Thanks in advance, as usual,
