Do you mean "compute the current density map of ERP data (at one
specific channel and latency) by computing the average of discrete
laplacian applied to unaveraged single-trial EEG data (at the same
specific channel and latency)".
Since the laplacian function is linear, it is the same as directly
computing the laplacian of the ERP at one specific channel and latency
(see my previous email on this subject this week using the function
