[Eeglablist] Analyzing ERSPs

Hello,

This question is not directly related to using EEGLAB, but has to do with
analyzing ERSPs.  What is an acceptable way to statistically compare ERSPs
within subjects over multiple sessions?  I have 10 subjects, where each
repeated the same task during 2 separate sessions.  I want to compare ERSP
amplitude over multiple sessions for each subject with ERSP amplitude over
many subjects within one session.  Does it make sense to run some type of
ANOVA at every time and frequency point or a MANOVA?  Or is there a better
way to compare two ERSPs taking into consideration the "pattern" of activity
over time and frequency (perhaps using a cluster-based permutation
strategy)?  Any thoughts would be greatly appreciated.

Thanks!
