We have several EEG and one MEG in our research center (www.bcbl.eu), and many projects with data already preprocessed. If somebody wants to play with it I can ask for (already preprocessed or raw) data. Most of the paradigms are language related though.
In any case, here you have software to analyze MEG and EEG data and example data as well: http://martinos.org/mne/stable/index.html (Matlab and Python, open source). In the hackaton I started playing with fMRI data too, far less data points than MEG (1 every 2 seconds aprox.), but I have yet to come back to the project, too busy right now. best regads, Gari On Jan 10, 2014 7:33 PM, "Hans Czylok" <[email protected]> wrote: > You are quite right.
