The easiest way to do this would be to run an EEG sample through 
the TimeStat program. (assuming you can work in windoze) 
It's very easy to use.
I know there are some databases for EEG data around, but have no 
references on hand. I can send you rat EEG, but that might not be 
what you had in mind.
