Maybe I am mistaken but it seems to me that the first output "laplac" of 
the "del2map" function contains exactly what you are looking for 
(del2map.m from EEGLAB 4.512). We recently modified this function so it 
is possible that older functions from previous EEGLAB distributions do 
not contain these recent changes.
