You have to look for the surface Laplacian under its other name, current
source density, where you see that we haven't implemented it yet but
it's on our todo list:

Hi MNE-experts,
i'm looking for the (small spatial) laplacian filter as described here:
https://dsp.stackexchange.com/questions/14220/large-laplacian-spatial-filter-on-eeg
<https://dsp.stackexchange.com/questions/14220/large-laplacian-spatial-filter-on-eeg&gt;
?
Is it implemented somehow in MNE? I just can't find anything similar
depending on channel neighborhood.
?
Thanks and best regards
Stephan
