I will get to the point, I have the following question:
-
I have EEG data (64 electrode arrays) from 30 subjects in 2 conditions: improvising a speech for 10 min or repeating a memorized speech for the same time. I also have 1 min baselines for both conditions.
-
As you can see, these data have no trials, they are a continuous record of 10 min per condition plus 1 min baseline.
-
My question is, what would be the best way to analyze this data in brainstorm (the data are already preprocessed and clean), thinking that I want to calculate power over EEG sources (I have localization obtained with polhemus fastrack) and compare statistically both conditions (I would like to use Desikan-Killiany for scout).
Please could you give me some guidance on this?
Thanks in advance!
