[Eeglablist] How to use laplacian filter by EEGLAB

[Ramesh Srinivasan]

Hi all -

I would like to toss in one more option - SSLTOOL, which was put 
together by Siyi Deng in my lab.  It does Laplacians on a sphere using a 
3-D spline detailed in papers and Nunez and Srinivasan (2006), but also 
can do Laplacians on a realistic 3-D MRI generated mesh using the 
methods described in our recent IEEE Transactions on BME paper.  I 
believe it plays nicely with EEGLAB data formats.
